Jamal-3 x 3 = 9 x 4 = 36
Andy- 4 x 2 = 8 x 5 = 45
Andy's surface area is bigger.
Answer:
1767 cm³
Step-by-step explanation:
We can use volume V = 4/3 π r³
We have diameter of 15 cm. To get radius, we need to divide diameter by 2.
r = 7.5 cm
So now plug in r = 7.5 then calculate V:
V = 4/3 π ( 7.5 )³
V = 4/3 π * 421.875 ≈ 1767.145 ≈ 1767
Hope this helps.
N=25 because 20 divided by 4 is 5 which is 1/5 of n meaning 5x5 is 25
How you do this problem is that you first find out how much the price has gone down.

Then, you divide 9.82 by the answer to your previous equation and then you have completed the question!
