The volume is proportional to the cube of the radius:
4^3=64
The volume will be 64 times the original value!
Answer:
a) 30 inches × 30 inches × 30 inches
b) 27,000 inches³
c) 14,130 inches³
d) 12,870 inches³
Step-by-step explanation:
Edge of the cube = diameter = 30 inches
Volume of cube = s³
30³ = 27000 inches³
Radius = 30/2 = 15
Volume of sphere:
(4/3) × 3.15 × 15³
14130 inches³
Difference:
27000 - 14130
12870 inches³
circumference = 2 x pi x r
using 3.14 for pi
2 x3.14x114=715.92
round to 716 yards
Answer: C
Step-by-step explanation:
the normal distribution is symmetric about its mean.
so answer c) must be true.
You just need to know that all sides need to have the same measurement because it is a equilateral triangle.
