Question
The diameter of a baseball is 7.4 cm. Use 3.14 for .a. Find the surface area to the nearest tenth of a square cm.b. Find the volume of the baseball to the nearest tenth of a cubic cm
Solution
a. The formula for the surface area of a sphere is 4πr². Given that the diameter of the baseball is 7.4 cm, the radius would be half of that, which is 3.7 cm. Substituting these values into the formula gives:
Surface Area = 4 * 3.14 * (3.7)² = 4 * 3.14 * 13.69 = 171.8 square cm (to the nearest tenth)
b. The formula for the volume of a sphere is 4/3πr³. Again, the radius is 3.7 cm. Substituting these values into the formula gives:
Volume = 4/3 * 3.14 * (3.7)³ = 4/3 * 3.14 * 50.653 = 211.9 cubic cm (to the nearest tenth)
