Area = pi*r2
1962.5 = pi * r2
divide both sides by pi
624.68 = r2
take square roots both sides
24.99 = r
2 * 24.99
= 49.98; the diameter

How do you calculate diamater with width and length?
diameter of a circle = 2*radius or circumference/pi
How do you solve the circumference of a circle?
to find the circumference of a circle, which is the distance in the outside of the circle you need to use the following formula: C=dx 3.14 or circumference equals diameter times pi. The diamater is the length of the circle from end to end. Not very difficult.
How do you find the area of a shaded circle and the area of an unshaded circle on that is inside the other circle?
To find the area of the circle pi*radius*squared and subtract the area of the figure inside
Is the circumference and area of a circle the same?
The circumference of a circle is the distance arround the edge of the circle. The area of a circle is how big the inside of the circle is.
Equation for area of a circle?
area of a circle = pi*r2
Area of a circle diamater of 6cm?
approximately 28.26 cm2
What is the area of a circle with diamater of 12 cm?
113.1 square cm
If the diamater of a circle is 18cm what is the area?
Area = pi*92 = 254.469 square cm to 3 dp
What is a area of a circle with a diamater with 4 cm?
Area = pi*22 = 12.566 square cm to 3 d.p.
What is the circumference of a circle with a diamater of 25m?
A circumference of 78.54m
How many square mm are in a 2mm diamater circle?
3.142
What is the circumference of a circle if the diamater is 4.6?
circumference = pi*4.6
How many square feet in a 40' diamater?

What is the circumference of a circle with 60 ft diamater?
The circumference of a circle with a 60-foot diameter is about 118.5 feet.
What is another way to find the area of a circle given the circumference?
Divide by pi to get the diameter. Divide the diamater by 2 to get the radius. Pi times radius squared.
Does a diamater sometimes always or never passes through the center of the circle?
Always
What is the circumference of a 18 foot diamater circle?
circumference = 18*pi feet
