V = (1/3)πr²h
V= 36π
h=12
36π=(1/3)πr²*12
36 =4r²
r² = 9
r = √9 = 3
Answer: r=3.

Answer:
Step-by-step explanation:
<u>We know that:</u>
- Side lengths of rectangular prism: 2 in, 5 in, and 6 in.
- Surface area = Area of all faces
<u>Solution:</u>
- Surface area = 2(6 x 2) + 2(5 x 2) + 2(6 x 5)
- => Surface area = 2(12) + 2(10) + 2(30)
- => Surface area = 24 + 20 + 60
- => Surface area = 104 in.
Hence, the surface area of the rectangular prism is 104 in.

Answer:
1 inch : 50 feet
Step-by-step explanation:
Usually when you are asked for a scale you need the first number to be a.
With that in mind, we simply have to bring 6 inches : 300 feet down to a 1 inch : 50 feet
aka 6/6 and 300/6
Answer:
b = (c-3a)/2
Step-by-step explanation:
3a+2b =c
Subtract 3a from each side
3a-3a+2b =c-3a
2b = c -3a
Divide each side by 2
2b/2 = (c-3a)/2
b = (c-3a)/2
