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 sq inches in a 16 inch radius?
To find the area of a circle in square inches, you can use the formula ( A = \pi r^2 ), where ( r ) is the radius. For a 16-inch radius, the area would be ( A = \pi (16)^2 = \pi \times 256 ). Thus, the area is approximately ( 804.25 ) square inches when using ( \pi \approx 3.14 ).
What is the area of a coin?
The area of a coin can be calculated using the formula for the area of a circle, which is A = πr², where A is the area and r is the radius of the coin. To find the area, you first need to measure the radius (half of the diameter) of the coin. Once you have the radius, square it and multiply by π (approximately 3.14). For example, if a coin has a diameter of 2 inches, its radius would be 1 inch, resulting in an area of approximately 3.14 square 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.
How many square inches are there in a 6 inch diameter circle?
To find the area of a circle, you use the formula A = πr^2, where r is the radius of the circle. In this case, the radius is half of the diameter, so the radius is 3 inches. Plugging this into the formula, we get A = π(3)^2 = 9π square inches. Since π is approximately 3.14, the area is approximately 28.26 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)
