Question about Adobe Photoshop 7.0 (321115627)

Ad

This sounds like someones homework. I'm risking my reputation here but here goes.

Previous Area was Pi x R x R. = Pi X 10 X 10 = 100 X Pi

Previous Perimeter is 2 X Pi X R = 2 X Pi X 10 = 20 X Pi

New shape is a rectangle with a semicircle at each end and width of 10 cm.

New Perimeter is circular bits + straight edges between them.

We know the circular bits but not how long the straight bits are so ...

Perimeter = 20 X Pi = (2 X Pi X 5) + L X 2 = 10 X Pi + (L X 2)

So L = (20 - 10) X Pi / 2 = 5 X Pi.

So the new Area is ... (Pi X 5 X 5) + (10 X 5 X Pi)

= 75 X Pi.

= 75 X 3.14 = 235.5

perimeter is 2X( L + B)

so that is 2 X (11+12)= 2 X 23 = 46 yards

area is LX B =11X12=132 square yards

grade 3 maths really

The radius or the volume of the space?

It varies by the shape. Anything sort of circular usually involves equations with Pi, but objects with corners are different. Since Fixya will not allow me to type equations very well here, I'll refer you to

First, I graphed the lines and the point using Desmos.com.

I noticed that the two lines are perpendicular to each other and the point (1,-1) appears to be on the right side of the circle, on a line parallel to 3x -4y-10=0. The equation of this line is y= 3/4x - 1.75. The y-intercept is -1.75. Now we have two points on the opposite sides of the circle, (1, -1) and (0,-1.75). The midpoint formula will give you the centre of the circle and the distance formula will provide the radius.

Let me know if you have any questions.

Good luck.

Since the area of a whole circle is pi times the radius squared, the area of half the circle is one half times pi times the radius squared.

Area - The size of a surface

Specific

Square

Area = Side x Side

Rectangle

Area = Length x Width

Triangle

Area = Base x Height (cut the answer in half and that is your area)

Parallelogram

Area = Base x Height

Circle

Area = Radius x Radius x 3.14

Hello,

You must have been taught the relation between the circumference (perimeter) of a circle, the radius and pi. Use it to calculate the perimeter. It is true for all circular figure.

Depending on what is really asked (the perimeter of the actual pool where you find the water, or the general pool area where no shoes are allowed)

**1st case:** use the radius that was given.

**2nd case: **the total radius is the radius given plus the width of the path.

If you do not have a formula for the perimeter that involves the radius, but have one that involves the diameter you can use it too, knowing that the diameter is twice the radius or the radius is one half of the diameter.

As you might have guessed I was not going to make things too easy for you by providing a ready-made answer, but I gave you** all the hints that will help you solve the problem**.

Hello,

Sorry to say it but the question does not make sense. A circle is a figure that is perfectly defined by the knowledge of its center (or centre depending of the English you use) and its radius.

An ellipse is perfectly defined if you know its two foci (plural of focus) and the length each of its two axes (major and minor).

Is it the perimeter, the area, the parameter p of the ellipse you are lookong for.

Hope it will help you focus on your real the question.(The pun is intended)

You cannot have a semicircle that has a diameter of 2.500 mm and a radius of .425mm and a circumference of 3000mm

Circumference is equal to pi times the diameter. pi is = 3.14

The radius of a circle is always 1/2 the diameter

Area of a circle is pi time the radius squared

Nice try!

If nobody has helped you since September 2008, when you asked the question, you probably scored a "zero" in your computer-programming course, and probably don't need an answer to your "homework" assignment.
