Sonia cut a tree trunk in the shape of a cylinder. The length is 15 feet, and the diameter is 30 inches. Solve for the surface area, using 3.14 for PI

Answer 1

The radius of the cylinder can be calculated by dividing the diameter by 2:
Radius = 30 inches / 2 = 15 inches

We need to convert the length from feet to inches:
Length = 15 feet x 12 inches/foot = 180 inches

Now we can calculate the surface area of the cylinder using the formula:
Surface Area = 2 * PI * radius * (radius + length)
Surface Area = 2 * 3.14 * 15 inches * (15 inches + 180 inches)
Surface Area = 2 * 3.14 * 15 inches * 195 inches
Surface Area = 9423 inches

Therefore, the surface area of the cylinder is 9423 square inches.
