How can you find area of a circle whose circumference is 44cm?
Radius of circle: 44/2*pi = 7 rounded Area of circle: pi*7 squared = 154 square cm rounded
How do you find the radius of a circle if you only know the area?
Radius = +sqrt(Area/pi)
What is the radius of a circle whose area is 616 square meters?
Well, isn't that just a happy little question! To find the radius of a circle when you know the area, you can use the formula A = πr^2. In this case, the area is 616 square meters, so you can plug that in and solve for the radius. Just remember to take a deep breath, trust in your math skills, and enjoy the process of finding the radius of this circle.
Find the radius of a circle whose area is 78.6 cm2?
A = (pi)r^278.6 = (pi)r^2r = 5.002 cm
Describe the effect on the area of a circle when the radius is doubled?
the radius is from the center of the circle to the edge so that's how you find the radius.
Find the area of a circle whose radius is 12 in?
Area = Pi(r)2 - A circle with a radius of 12 inches has an area of 452.39 square inches.
Find the area of a circle whose radius is 25 inches?
Area = Pi(r)2 - A circle with a radius of 25 inches has an area of 1,963.5 square inches.
How do you find the area of a circle whose radius is 12 centimeters?
Area = Pi(r)2 - A circle with a radius of 12 centimeters has an area of 452.39 square centimeters.
Find the area of a circle whose radius is 5 inches?
pi*25 = 78.5.
Find the area of the circle whose radius is 8 miles?
64pi (miles square)
How do you find ratio of area to radius?
In a circle, the area of the circle is pi times the radius squared
What is the radius and the area of a circle?
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
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
Why do you find the area of a circle with pi times the radius squared?
You find the area of a circle with pi times radius squared because the radius is half the circle so to find the full area you need to multiply it again.
How can you find area of a circle whose circumference is 44cm?
Radius of circle: 44/2*pi = 7 rounded Area of circle: pi*7 squared = 154 square cm rounded
How you can find the radius of a circle whose circumference is b?
radius = b/2*pi
How do you find the radius of an inscribed circle of a square given the area of the circle?
If yo have the area of the circle, the square is irrelevant. Radius = sqrt(Area/pi)
