Hey!
To find the percentage increase, you must use this formula:
{(50 - 92 / 50] × 100 = 84%
So, the percent increase from 50 to 92 is: 84%.
Answer:
32
Step-by-step explanation:
let number=b
twice a number=2b
Condition:
2b+13=75
2b=75-13
2b=62
b=62/2
b=31

To solve for radius use the volume formula and solve for r.
V = πr²h
320π = πr²(20)
320π/π = 20r²
320 = 20r²
320/20 = r²
16 = r²
√16 = r
4 = r
Answer is D. 4 feet.
Hope this helps :)
