What are the surface area and volume of a softball with a radius of 1.90 inches?
The surface area of a sphere can be calculated using the formula A = 4πr² and the volume can be calculated using the formula V = (4/3)πr³, where r is the radius of the sphere.
The given radius of the softball is 1.90 inches.
Surface Area Calculation:
Surface Area formula: A = 4πr²
Plugging in the radius of 1.90 inches:
A = 4π(1.90)² = 15.08in²
Therefore, the surface area of the softball is approximately 15.08 square inches.
Volume Calculation:
Volume formula: V = (4/3)πr³
Substituting the given radius:
V = (4/3)π(1.90)³ ≈ 9.06in³
Hence, the volume of the softball is approximately 9.06 cubic inches.
Therefore, the correct answer is A) Surface Area: 15.08in², Volume: 9.06in³.
