Answer:
if 1in=15miles
then20.4in=? miles
1in by ? miles and 20.4in by 15miles
1in ? miles= 306in miles
divide both sides by 1in
? miles= 306 miles
therefore 20.4in = 306miles
5.3 to the 4th power :)
Step-by-step explanation:
take them seriously, they weren't a joke
Volume of a sphere = 4πr³/3
r=10
V = 4πx10³/3
=4000π/3
V= 1333.33π (in terms of pi)
or
V= 4188.79(Nearest Hundredth).
