Ответ:
D. 0.8
Step-by-step explanation:
The formula for finding the volume of cylinders is:
V= (pi)(r^2)(h)
r is the radius and h is the height. V is the volume.
plug in the values.
375 = (3.14)(12.5^2)(h)
375 = (3.14)(156.25)(h)
375 = 490.625 x h
Divide both sides of the equation by 490.625
0.7643... = h
round the decimal to the tenths place and get 0.8
