Answer:
V = 2304π units³
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = 
πr³ ( where r is the radius ) , then
V = π × 12³
= π × 1728
= 4π × 576
= 2304π units³

Here is the ans..hope it helps:)
Answer:
12 and 28
Step-by-step explanation:
Represent the numbers using x and y. Then y - x = 16. (y is the larger one.)
Then 3y = 7x, and y = (7/3)x.
Substituting (7/3)x for y in y - x = 16, we get:
(7/3)x - x = 16.
Eliminate the fraction by multiplying all three terms by 3:
7x - 3x = 48, or 4x = 48, yielding x = 12. Then y = (7/3)(12) = 28.
The reciprocal is 17/2 cause all you do is just flip the fraction

Estimate
Step 1: Estimate the square root of 2:
1.4x1.4=1.96
1.41x1.41=1.9881
1.42x1.42=2.0164
1.9881 is closer to 2 than 2.0164
Square root of 2 is about 1.41
Step 2: Multiply the answer in step 1 by 8
1.41x8=11.28
8 times square of 2 is about 11.28
Square root of 128 is about 11.28
If you put square root of 128 in a calculator it would say 11.31 something...
