There is no single, correct, answer to this question.

For example, if the three circles overlap 99%,

then the combined area will only be about 1% larger

than the area of a single circle.

If the circles only slightly overlap, then the combined area will be much larger than the area of one circle.

What is the question?

A circle with a radius of 3 kilometers has a perimeter of about 18.85 kilometers and an area of about 28.27 square kilometers.

(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

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

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.

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 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

how big is the triangle? if the coins are a mile in diameter doesnt mean you cant have an equilateral triangle with legs of 32 miles long.

or are you asking for the equation?

i will send you on the path to the equation.

if you draw a circle on a piece of paper then draw a triangle around it where is the center? if the triangle were a perfect equilateral then the circle would be a perfect circle touching the sides of the triangle.

its important to know where the center is because the center of the circle to the edge of the circle is the radius.

so the center of a triangle is the center of the circle. therfeore the radius of the circle will equal hieght/2...

thinking that way you can say that if there were three coins then the center of the triangle cant be occupied by a coin but is very close to an edge. where is the center of the coin?

You sort out the formula for the surface you have to calculate then substitute the numerical values for the variables (sides, bases, heights), the constants if any (pi, etc.) an press = to get the result

Ex Square with side= 2m

Surface area=side^2

Area : 2 [X^2][=] result is 4 m^2

Circle of radius r=3 cm

Area: Pi* 3[^2]=28.27 cm^2

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
