Answer:

V = 6373.2cm^3

Step-by-step explanation:

Given

V = \frac{4}{3}\pi r^3 --- Volume

D = 23cm --- Diameter

Required

Find the volume

First, we calculate the radius, r

r = \frac{1}{2}D

Substitute 23 for D

r = \frac{1}{2} * 23

r = 11.5

Substitute 11.5 for r in V = \frac{4}{3}\pi r^3

V = \frac{4}{3} * \frac{22}{7} * 11.5^3

V = \frac{4*22*11.5^3}{3*7}

V = \frac{133837}{21}

V = 6373.19047619

V = 6373.2cm^3

A painter is hired to paint the interior walls of a large warehouse. The function f(x)=20,000−40x models the area in square feet
Leto [7]

Insert x = 100 and x = 200 in the function

f(100) = 20,000 - 40*100

= 20,000 - 4000

= 16,000


f(2)) = 20,000 - 8,000 = 12,000

So its choice C  ,  All reals between 12,000 and 16,000 inclusive.
