how to find the volume of each sphere, both in terms of \pi and the nearest tenths for r=3 use 3.14 for \p.

Answers

Volume formula of a sphere:
$(4)/(3)$ $\pi$ r³

given:
r = 3

V = $(4)/(3)$ $\pi$ (3)³
V = $(4)/(3)$ × 27 $\pi$
V = 36 $\pi$ units³ (in terms of $\pi$ )
V = 113.097 units³ ≈ 113.1 units³

4 feet
each friend gets 1/3 foot
if you wante to do $(4)/( (1)/(3) )$
try to make bottom number=1
1/3 times 3/1=3/3=1
multiply the whole thing by $( (3)/(1) )/( (3)/(1) )$

$(4*3)/( (3)/(3) )$
$(12)/( 1)$

12

Okay, I would multiply 4 times 12 since there is 12 inches in a foot and then divide it by 3. which the answer would be 16 inches.

Find the mean 10,12,17,14,20,27,24,28,28

Answers

Hi Kimberlys969pdrfzz,

Question:

Find the mean

Mean - "The mean is the average of the numbers: a calculated "central" value of a set of numbers. To calculate it: add up all the numbers, then divide by how many numbers there are."

Solution:

$(10 + 12 + 17 + 14 + 20 + 27 + 24 + 28 + 28)/(9) = (180)/(9) = 20$

Answer:

Mean = 20

Hope This Helps!

10 + 12 + 17 + 14 + 20 + 27 + 24 + 28 + 28 = 180/9 = 20

mean: 20
