Find the area of the given circle.Round to the nearest tenth.
The diameter of the circle is 12 feet.
A.11.0 ft^2
B.38.5 ft^2
C. 42.8 ft^2
D. 113.20 ft^2
Is the answer D?
Thank you
area=PI (D/2)^2 yes D
I need the answers
plz give all answers brother
Well, let's find out! To calculate the area of a circle, we use the formula A = πr^2, where A is the area and r is the radius. Since the diameter is given, we can divide it by 2 to get the radius. So, the radius is 12/2 = 6 feet. Now, let's plug that into the formula:
A = π(6)^2 = 36π ≈ 113.1 ft^2
So, the correct answer would be D, 113.1 ft^2. Nice try!
To find the area of a circle, you can use the formula:
Area = π * (radius)^2
The radius of a circle is half the diameter. In this case, the diameter is given as 12 feet, so the radius would be 12/2 = 6 feet.
Substituting the value of the radius into the formula, we get:
Area = π * (6)^2
Now, the value of π is approximately 3.14, so we can use this approximation:
Area = 3.14 * (6)^2
Calculating the value of the area, we get:
Area = 3.14 * 36 = 113.04
Rounding this to the nearest tenth, we get 113.0.
Therefore, the correct answer is A. 11.0 ft^2, not D. 113.20 ft^2.
