Answer:
C. 
Step-by-step explanation:
The volume of the ball with radius R can be calculated using formula

A basketball has a diameter of 9.5 cm, so its radius is

Hence, the volume of air the basketball can hold is

Attached you will see the solution using the trig plane and general solutions.
If I think I’m understanding it, the new members out of the 200 original would be adding 28% to the mix
It translates to
which solves to
after dividing both sides by 78. This means n is equal to 4 or it can be larger than 4.
Answer:
2*10 ^6 shoes in 10 years
Step-by-step explanation:
1.81 × 10^4 pairs of shoes each month
1.2 × 10^2 months in 10 years
Multiply these together to determine the number of shoes in 10 years
1.81 × 10^4 * 1.2 × 10^2
We want to estimate so 1.81 is approximately 2 and 1.2 is approximately 1
2 × 10^4 * 1 × 10^2
Multiply the numbers
2*1 = 2
Add the exponent
10 ^ ( 4+2)
10 ^6
Put this back together
2*10 ^6
