surface area of cylinder radius of 5 height of 7.5 rounded to nearest hundreth use 3.14 for pi
To find the surface area of a cylinder, you can use the formula:
Surface area = 2πr(r + h)
Given:
Radius (r) = 5
Height (h) = 7.5
Substitute the values into the formula:
Surface area = 2 * 3.14 * 5(5 + 7.5)
Surface area = 2 * 3.14 * 5(12.5)
Surface area = 2 * 3.14 * 62.5
Surface area = 125 * 3.14
Surface area ≈ 392.5
Therefore, the surface area of the cylinder with a radius of 5 and a height of 7.5 is approximately 392.5 square units.
