Sonia cut a tree trunk in the shape of a cylinder. The length is 15 feet and the diameter is 30 inches solve the surface area using 3.14 for pi.
127.52,826
274.75
117.75
To find the surface area of the cylinder, we need to first find the radius of the cylinder. The diameter is given as 30 inches, so the radius is half of the diameter, which is 15 inches.
Now, we can calculate the surface area using the formula:
Surface Area = 2 * π * radius * (radius + length)
Plugging in the values:
Surface Area = 2 * 3.14 * 15 * (15 + 15)
Surface Area = 2 * 3.14 * 15 * 30
Surface Area = 1884 square inches
So, the surface area of the cylinder is 1884 square inches.
