The diameter of a circle is 32 feet. What is the circle's area?
d=32 ft
Use 3.14 for 𝜋
The radius of the circle is half of the diameter, so:
r = d/2 = 32/2 = 16 ft
The area of the circle is:
A = πr^2 = 3.14 x 16^2 = 3.14 x 256 = 804.24 square feet
Therefore, the circle's area is approximately 804.24 square feet.
The diameter of a circle is 2 feet. What is the circle's area?
d=2 ft
Use 3.14 for 𝜋.
The radius of the circle is half of the diameter, so:
r = d/2 = 2/2 = 1 ft
The area of the circle is:
A = πr^2 = 3.14 x 1^2 = 3.14 square feet
Therefore, the circle's area is approximately 3.14 square feet.
To find the area of a circle, you can use the formula:
Area = 𝜋 * (radius)^2
Given that the diameter of the circle is 32 feet, we can find the radius by dividing the diameter by 2:
radius = diameter / 2 = 32 ft / 2 = 16 ft
Now we can substitute the radius value into the formula to find the area:
Area = 3.14 * (16 ft)^2
= 3.14 * 256 ft^2
= 803.84 ft^2
Therefore, the circle's area is approximately 803.84 square feet.
