What equation can be used to find the area in square inches of a circle with a radius of 8 inches?
Area of the circle in square inches = pi*82
Find the circumference and area of a circle with radius of 5 inches?
Circumference = 31.4 inches, approx. Area = 78.5 square inches, approx.
What could be used to find the area in square inches of a circle with a radius of 10 inches?
Pi x Radius x Radius = Area 3.1415 x 10 x 10 = 314.15 in^2 (for more accuracy, find more exact values of Pi)
How many square inches are in an 12 inch round circle?
First find the radius = 12/(2*pi) = 1.909859317 inches Area = pi*1.9098593172 = 11.4591559 or about 11.5 square inches
What quadratic equation can you use to find the radius of a circle when the area is 100 inches squared?
pi*radius2 = 100 square inches Making the radius the subject of the above equation gives it a value of 5.641895835 inches.
Find the area of a circle with a radius of 9 inches?
254.47 square inches.
What equation can be used to find the area in square inches of a circle with a radius of 8 inches?
Area of the circle in square inches = pi*82
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.
What is the area of a circle is 173 square inches find the radius?
r = 7.421 inches.
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.
If the area of a square is 72 inches squared find the radius?
A square doesn't have a radius. A circle has. If the area of a square is 72 inches2, then each of its sides is 6 sqrt(2) = 8.485 inches. (rounded)
Which equation could be used to find the area in square inches of a circle with a radius of 8 inches?
Area = (radius)2 x pi Area = 82 x pi Area = 64 x pi Area ≈ 201.06 square inches
Find the circumference and area of a circle with radius of 5 inches?
Circumference = 31.4 inches, approx. Area = 78.5 square inches, approx.
The circumference of a circle is 18pi inches Determine the area of the circle?
First we have to find the radius: 2*pi*radius = 18*pi Divide both sides by 2*pi to find the radius: radius = 9 inches Area of a circle = pi*radius2 Area = pi*92 = 81pi or 254.4690049 square inches
What is the area of a circle with a diameter of 60 inches?
To find the area of a circle, you use the formula A = πr^2, where r is the radius of the circle. Since the diameter is 60 inches, the radius is half of that, which is 30 inches. Plugging this into the formula, A = π(30)^2 = 900π square inches. Therefore, the area of the circle is 900π square inches.
What could be used to find the area in square inches of a circle with a radius of 10 inches?
Pi x Radius x Radius = Area 3.1415 x 10 x 10 = 314.15 in^2 (for more accuracy, find more exact values of Pi)
How long is the radius in a circle with area of 50.24 square inches?
To find the area of a circle you take the square of the radius and multiply by pi. The formula is = Radius2 x 3.14 = Area. So, to find the radius, you reverse the formula. Divide 50.24 by pi, which equals 16. So Radius2 = 16. The which means the radius is the square root of 16, or 4. Check your work, (4 x 4) x 3.14 = 50.24. The radius is 4 inches.
