Determine the area of the lateral face of the cylinder below. Round your answer to the nearest whole number. Use 3.14 for PI.
the cylinder angles are 10 in, and 3 in
A. 30 square inches
B. 94 square inches
C. 251 square inches
D. 817 square inches
To find the lateral surface area of a cylinder, you need to use the formula 2 * pi * r * h, where r is the radius of the base of the cylinder and h is the height of the cylinder.
Given that the radius is 5 in (half of the diameter which is 10 in) and the height is 3 in, we can substitute these values into the formula.
Lateral surface area = 2 * 3.14 * 5 * 3
Lateral surface area = 94.2 square inches
Rounded to the nearest whole number, the lateral surface area is approximately 94 square inches.
Therefore, the correct answer is:
B. 94 square inches
