The radius of a cylinder is 5 inches. The height of the cylinder is 7.5 inches. Determine total area of two bases. Round your answer to the nearest hundredth (Use 3.14 for π.) A. 19.63 square inches. B. 39.25 square inches. C. 78.50 square inches. D. 157.00 square inches.
The formula for the area of a circle is A = πr^2, where r is the radius of the circle.
Given that the radius of the cylinder is 5 inches, we can calculate the area of one base as follows:
A = π(5)^2
A = 25π
A ≈ 78.54 square inches
Since there are two bases, the total area of two bases would be:
2 * 78.54 = 157.08 square inches
Rounded to the nearest hundredth, the total area of two bases is approximately 157.00 square inches.
Therefore, the correct answer is D. 157.00 square inches.
