Find the surface area of a cylinder with a radius of 4 cm and a height of 2 cm. Use the approximation of 3.14 for pi.

Answer 1

The formula for the surface area of cylinder is given by:

Surface Area = 2πr^2 + 2πrh

Given that the radius (r) is 4 cm and the height (h) is 2 cm, we can substitute these values into the formula and calculate the surface area.

Surface Area = 2π(4^2) + 2π(4)(2)

Surface Area = 2π(16) + 2π(8)

Surface Area = 32π + 16π

Since the approximation of π is given as 3.14, we can substitute this value into the equation.

Surface Area = 32(3.14) + 16(3.14)

Surface Area = 100.48 + 50.24

Surface Area ≈ 150.72 cm^2

Answer 2

whats the square centimeters?

Answer 3

The surface area of the cylinder is approximately 150.72 square centimeters.

Answer 4

Find the surface area of a cylinder with a diameter of 12 inches and height of 10 inches. Use the approximation of 3.14 for pi.(1 point)
