What is the area of a circle with a radius of 7 meters?
3850m is the area of the a circle whose radius of 7meaters
How do you find the radius of circle with area 144pi?
Equation for the area circle = pi x radius squared If the area is 144pi, then you need to find the square root of 144, which is 12. Therefore, radius = 12
What is the area of a circle if the radius is 5 cm?
The area of a circle, if the radius is 5 cm, is: 78.54 cm2
What is the approximate area of a circle with a radius of 11 m?
A circle with a radius of 11m has an area of ~380.13 m2
What is the area of a circle with the radius of 13?
A circle with a radius of 13 units has an area of 530.93 square units.
How do you find the area of a circle by only knowing the radius?
Since the area of a circle is pi times radius squared, take the radius and square it. Then, multiply that by 3.14, or pi to get the area of the circle.
How do you find the circumference of a circle without knowing the radius and area?
You will have to measure some part of the circle. As long as you have absolutely no information about a circle, you can't do any calculations.
What is the square footage of a 10 foot radius circle?
Knowing that the area of a circle is its radius squared times Pi, the area of a 10 ft radius circle is 100*Pi square ft, or about 314 square feet.
How do you find the circumference of a circle without knowing the area?
To find the circumference of a circle, you need only know the radius or diameter of the circle. The circumference of a circle is calculated as 2 x Pi x radius OR Pi x diameter. Pi is approximately 3.1415926.
How do you find the area of a semi circle knowing the radius?
count the number of sides?
Why it is so important to know the area of a circle?
Knowing the area of a circle which is pi times radius squared will help you to find other properties of the circle
How can you determine the area of a circle by using the radius squared and without finding the radius?
The area of a circle is pi * radius2. If you already have the radius squared, you just have to multiply that by pi.
Why is it so important to know the circumference of a circle when finding the surface area of a cylinder?
It is not. Knowing its radius or diameter will do just as well.It is not. Knowing its radius or diameter will do just as well.It is not. Knowing its radius or diameter will do just as well.It is not. Knowing its radius or diameter will do just as well.
How do you find the area of a circle only knowing the radius?
If you know the radius (say it's 4), square the radius and multiply that number by pi. So for a radius of four, it would be 4 X 4 = 16 X 3.14 = 50.24, the area of the circle.
What is the area of a circle if the radius is 9m?
The area of a circle if the radius is 9m 254.5m2
What is the radius of a circle with the area of 36?
The radius of a circle with the area of 36 is 3.385
What is the area of a circle with the radius of 21?
The area of a circle of radius 21 is 1386
