find the area of each circle to the nearest tenth with diameter of 8ft.
To find the area of a circle, we can use the formula:
Area = π * (radius)^2
Since you have the diameter of the circle, and the radius is half the diameter, we can start by finding the radius.
Given that the diameter is 8 feet, we can calculate the radius as:
radius = diameter / 2
= 8 ft / 2
= 4 ft
Now, we can plug the radius into the formula to find the area:
Area = π * (radius)^2
= π * (4 ft)^2
= π * 16 ft^2
To calculate the area to the nearest tenth, we need to approximate the value of π. Let's use 3.14 as an approximation for π.
Area ≈ 3.14 * 16 ft^2
≈ 50.24 ft^2
Therefore, the area of the circle is approximately 50.24 square feet.
A = pi * r^2
Plug in the numbers and solve. What do you get?
