Find the surface area of a sphere with a radius of 3.6 ft. Use 3.14 for pi. Round your answer to the nearest hundredth, if necessary.(1 point) The surface area is ft.^2
The formula for the surface area of a sphere is A = 4πr^2, where r is the radius of the sphere.
Plugging the given values, we get A = 4 * 3.14 * (3.6 ft)^2.
Calculating the expression, we find A = 4 * 3.14 * 12.96 ft^2.
Thus, the surface area of the sphere is 162.864 ft^2.
Rounded to the nearest hundredth, the surface area is 162.86 ft^2. Answer: \boxed{162.86}.
To find the surface area of a sphere, you can use the formula A = 4πr^2, where A is the surface area and r is the radius of the sphere.
Given that the radius is 3.6 ft and π is approximately 3.14, we can substitute these values into the formula to calculate the surface area.
A = 4πr^2
A = 4 * 3.14 * (3.6)^2
A = 4 * 3.14 * 12.96
A ≈ 162.86 ft^2
Therefore, the surface area of the sphere with a radius of 3.6 ft is approximately 162.86 ft^2.
The formula for the surface area of a sphere is given by A = 4πr^2, where r is the radius of the sphere.
Substituting the given values, we get A = 4 * 3.14 * (3.6 ft)^2.
Plugging the value of the radius, we have A = 4 * 3.14 * 12.96 ft^2.
Calculating the expression, we find A = 162.3744 ft^2.
Rounded to the nearest hundredth, the surface area of the sphere is 162.37 ft^2. Answer: \boxed{162.37}.
