Here is your answer
D. 
π 
REASON:
Formula for volume of sphere
= 4/3×π× r^3
Here, r= 13
So,
volume=4/3×π× 13^3
= 4/3×π× 2197
= 8788/3 ×π

Answer
$40
Explanation
Because the perfume is on sale (70% off), it only costs 30% of its original price.
So we divide the sale price of the perfume ($12) by 30%
12 ÷ 30 = 0.4
Then, we multiply 0.4 by 100
0.4 × 100 = $40
I hope it's correct
Step-by-step explanation:
First no. is 12
Second no. is 8
Third no. of 25
Way 1 of grouping the numbers,
(12×8)×25
We can use associative law of multiplication as follows :
(a×b)×c = a×(b×c)
(12×8)×25 = (96) × 25
= 2400
Way 2,
12×(8×25) = 12 × 200
= 2400
Way 2 is easier to simplify because when we multiply 8 and 25, we get 200. It is very easy to multiply any number with a number that have zeroes. As a result we easily get the answer i.e. 2400.
Okay so you need to calculate all of the numbers together
