Answer:
2.05 inches
Step-by-step explanation:
V = 4/3 x πr³
36=4πr³/3
36x3= 4πr³
108= 4πr³
108/4 = πr³
27= πr^3
27/π =r³
r=
![\sqrt[3]{27 \div \pi}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B27%20%5Cdiv%20%5Cpi%7D%20)
r= 2.048in
round off to 2.05in
<u>PROOF</u>
V = 4÷3 x πr³
V= 4/3 x π(2.05)³
V=4/3 x π8.6
V=4×π×8.6/3
V=108/3
V=36in³
Therefore: radius= <u>2.05 inches</u>
I think its 9.
I hope this helps!!!
1: 2x+y=3
5x-2y=12
2: Multiply the first equation by 2
(2) (2x+y=3) => 4x+2y=6
3: Add
4x+2y=6
+ 5x-2y=12
______________
9x=18 The y's cancel out
9x/9=18/9 The 9's cancel out
x=2
4: Plug (x=2) back into either equation but, I'm going to do the first one. It's easier.
2(2)+y=3
4+y=3
4-4+y=3-4 The 4's cancel out
y=-1
Answer: (12,-1)
If you plug (x) and (y) back in it will equal 3 for the first and 12 for the second.
Answer:
16.5 is the area
