A sphere with a radius of 5 cm is enlarged by a scale factor of 2. What is the approximate volume of the new sphere in cubic inc
1 answer:
Answer:
255.61 inch³
Step-by-step explanation:
Volume of sphere is given by
V = πr³
Given that the original sphere had a radius of 5 cm, and that this is enlarged by a scale factor of 2, the new radius is
r = 5 cm x 2 = 10 cm
since 1 cm = 0.3937 inches, (need to convert to inches)
10 cm = 3.937 inches
hence r = 3.937 inches
V = x π x 3.937³
= 255.61 inch³
