The volume of the tennis ball with a radius of 2.1cm³ is 38.8cm³
The volume of the golf ball with a radius of 2.0 cm³ is 33.5cm³
Complete question:
Find the volume of each ball. use the formula. where v is the volume and r is the radius. record the volume in table A of your student guide. the radius of the tennis ball is 2.1cm and the radius of the golf ball is 2.0cm. the formula is V = 4πr³/3
Given the formula for calculating the volume expressed as:
[tex]V = \dfrac{4 \pi r^3}{3}[/tex]
For the tennis ball
radius = 2.1cm
Substitute the given values into the formula
[tex]V_t = \dfrac{4\pi (2.1)^3}{3}\\V_t = \dfrac{4 \times 3.14 \times 2.1^3}{3}\\V_t = \dfrac{116.31816}{3} \\V_t = 38.77cm^3[/tex]
Hence the volume of the tennis ball is 38.8cm³
For the golf ball
radius = 2.0cm
Substitute the given values into the formula
[tex]V_t = \dfrac{4\pi (2.0)^3}{3}\\V_t = \dfrac{4 \times 3.14 \times 2.0^3}{3}\\V_t = \dfrac{100.48}{3} \\V_t = 33.49cm^3[/tex]
Hence the volume of the tennis ball is 33.5cm³
