worty [1.4K]

Answer:

720,682.92

Step-by-step explanation:

8.5% = 0.085

P(t) = Initial Population * (1 + rate)t

P(t) = 230,000(1 + 0.085)t

P(t) = 230,000(1.085)t

P(14) = 230,000(1.085)14

P(14) = 720,682.82

What is the volume of the cone shown below?

STatiana [176]

The formula to calculate the volume of a cone is:

$V= \frac{1}{3} \pi (radius)^2h$

So, replace radius = 3in and h = 8 in.

The result is: [1/3] π (3in)^2 (8in) = [1/3]π(9)(8) in^3 = 24 π in^3

Answer: option b. 24 π in^3
