The lateral face of a cylinder can be calculated using the formula 2πrh, where r is the radius of the base and h is the height of the cylinder.
In this case, the radius is half of the line going straight across the top, so it is 10/2 = 5 inches.
Plugging in the values:
2 * 3.14 * 5 * 3 = 94.2 square inches
Rounded to the nearest whole number, the area of the lateral face of the cylinder is 94 square inches.
Determine the area of the lateral face of the cylinder below. Round your answer to the nearest number. Use 3.14 for pi.
Line going straight across the top: 10 inches
height 3
