Find the volume of the specified solid. Use 3.14 as the approximate value of r, and round your answer to the nearest tenth.
Find the volume of a cylinder with radius 5 cm and height 8 cm.
The formula for the volume of a cylinder is given by V = πr^2h, where r is the radius and h is the height.
Using r = 5 cm and h = 8 cm, we can substitute these values into the formula to find:
V = π(5 cm)^2(8 cm)
V = π(25 cm^2)(8 cm)
V = 200π cm^3
Since we are given to use 3.14 as the approximate value of π, we can substitute π ≈ 3.14 to find the approximate volume:
V ≈ 200(3.14) cm^3
V ≈ 628 cm^3
Rounding to the nearest tenth, the volume of the cylinder is approximately 628 cm^3.
