(pi)R squared (Fixya won't let me use the sign for Pi)

Area of a circle=pi*radius^2 or pi times radius times radius

example: suppose the radius of a circle is 10 inches, then the Area of the circle would be pi times 10 times 10 or 100*pi

pi represents the circumference (distance around) of a circle / diameter and for any circle is constantly the same number which is approximately 3.14

so in my example 100*pi=100*3.14 or 314 square inches

Area of a circle=pi*radius^2 or pi times radius times radius

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.

I will not try to guess what that diameter represents, so I will give you all mensuration formulas for the area of a regular polygon.

**s** is the measure of the side,** r** the radius of the inscribed circle, **R** the radius of the circumscribed circle, and **n** the number of sides.

If the angle unit in your calculator is the degree, use 180 instead of Pi. Use the formulas with PI if angle unit is set to radians.

In the formulas on the last line of the display screen (the formulas with sine functions) the radius r should be R (circumscribed circle radius). cot is the reciprocal of the tangent function**(cot(x)=1/tan(x) )**

Try it. Area is equal to pi (3.1417) multiplied by the square of the radius.

At 4.5 in. A=63.585 sq in

At 9 in. A=254.34 sq in

What do you think?

The circumference of a circle is given by the expression

Circumference= 2* PI* Radius of circle

**C=2*Pi*R**

The area is given by

**Area of a disk with radius R** **= Pi* R*R** or **PI*R^2**

**Area= PI*R^2**

Circumference= 2* PI* Radius of circle

The area is given by

The diameter of the circle is the diagonal of the rectangle use Pythagoras this rectangle is a made from two 3,4,5 triangles, so the diameter is 5cm, the radius will be 2.5cm don't forget the BODMAS ordering rule (Brackets of Division Multiplication Addition and Subtraction) Also rounding to 2 decimal places. This solution is based on all four corners of the rectangle touching the circumference of the circle.

Area of a circle is P (22/7) i x Radius (squared ^2) ====> 22/7 x 2.5cm ^ 2 ====> 22/7 x 6.25cm

TOTAL AREA of CIRCLE = 19.64 cm^2

Area of the rectangle is length x width ====> 4 cm x 3 cm

TOTAL AREA of RECTANGLE = 12 cm ^2

The remaining portion is the circle area minus the rectangle 19.64-12 = 7.64 cm^2

Hello my friend, I am Jonas I work as a programmer in some various programming languages. Here try this code:

This program is design to output the Diameter, circumference, and area given a radius of a circle. #include <iostream.h> int main() { int radius, diameter, circumference, area, pi; cout << " Enter the radius of a circle\n"; cin >> radius; pi = 3.14159; diameter = 2 * radius; circumference = 2 * pi * radius; area = pi * (radius)^2; cout << "Diameter formula executing.....(2 x r)\n"; cout << "Diameter is " << diameter << endl; cout << "circumference formula executing.....(2 x pi x r)\n"; cout << "circumference is " << circumference << endl; cout << "area formula executing......(pi x [r x r])\n"; cout << "area is " << area << endl; return 0; }

Also if you need tutorial you can visit this site Learning C++ .Hope this solution will able to help your problem solved. If you need more assistance just reply to this post or send me a mail at geo_jonas@yahoo.comThank you and Godbless.

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
