Answer:

b

Step-by-step explanation:

The volume (V) of a sphere is calculated as

V = \frac{4}{3}πr³ ( where r is the radius )

Here r = 3, thus

V = \frac{4}{3}π × 3³

   = \frac{4}{3}π × 27 = 4π × 9 = 36π in³ → b

8th graders can solve 7 problems in 14 minutes. How long with it take them to solve 37 problems?
xxMikexx [17]

Answer:

74 minutes

Simple Solution:

If you use common sense you can just look at the ratios and find that 14 is 7 twice. You apply the same pattern to 37 and you get 74.

Explanation:

Convert the word problem into proportional relationships (Ratios). You should get (7/14) and (37/?). Divide 37 by 7 (Use a calculator for this). Multiply the quotient by 14 to get a final answer of 74.
