How do you figure out the area of a circle?
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
What is the area of a circle whose radius is 4 inches?
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
How do you find the area of diameter of a circle?
Area of a circle = pi times radius squaredDiameter of a circle = 2 times radius
What is formular of circle?
Area of a circle: pi times radius squared Circumference of a circle: 2 times pi times radius or diameter times pi
What is the the length of a circle that has a radius of 30?
The circumference of a circle with radius 30 is equal to 2 times the radius times pi, or about 188.5.
Formula of circle?
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.
What is diameter and 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.
Number of square units occupied by the space inside a circle?
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.
How do you calculate diameter of a circle if you know the radius?
the diameter of a circle is two times the radius
How you get the area of a circle?
A= Area of the circle¶= Pi (About 3.14)r= Radius squared (Radius times radius)3.14 * Radius squared
Why is the circumference of a circle diameter times pi or 2 radius times pi?
Because 2 times the radius is equal to the diameter of the circle
How do you find ratio of area to radius?
In a circle, the area of the circle is pi times the radius squared
