A sporting goods company used 904.39 cubic inches of air to inflate a red rubber ball. What is the radius of the ball
1 answer:
Answer:6.0002inch
Step-by-step explanation:
Volume of sphere=904.39
π=3.14
Volume of sphere=4/3 xπ x r^3
904.39=4/3 x 3.14 x r^3
904.39=(4x3.14xr^3) ➗ 3
904.39=(12.56xr^3) ➗ 3
Cross multiplying we get
904.39x3=12.56xr^3
2713.17=12.56xr^3
r^3=2713.17 ➗ 12.56
r^3=216.02
Taking the cube root of both sides
r=3√216.02
r=6.0002
