A= about 2.14( also known as pi) times r( radius) squared( to the second power or r times r) Pi is actually about 3.14

4 to the second power is 16 and pie is always 3.14 so pie times radius so multiply 3.14 and 16 and that is your answer 50.24 answer

Area of a circle = pi times radius squaredDiameter of a circle = 2 times radius

Area of a circle: pi times radius squared Circumference of a circle: 2 times pi times radius or diameter times pi

The circumference of a circle with radius 30 is equal to 2 times the radius times pi, or about 188.5.

The formula for the area of a circle is pi times the radius squared. The formula for the circumference of a circle is two times pi times the radius.

the radius is a line from the middle of a circle to a point of the circle. the diameter is two times the radius.

This is the definition of the area of a circle. The formula to find area is given as pi times the radius raised to the second power, where pi is approximated as 3.14.

the diameter of a circle is two times the radius

A= Area of the circle¶= Pi (About 3.14)r= Radius squared (Radius times radius)3.14 * Radius squared

Because 2 times the radius is equal to the diameter of the circle

In a circle, the area of the circle is pi times the radius squared
