Answer:
3b^7a^6c^9/64
Step-by-step explanation:
I got 65/153 since you actually multiply by the reciprocal of the second fraction.
Answer:
add 12 +9 because i had that same answer on my quiz last week
The answer is 3 ft
The surface area (SA) of a cylinder with radius r and height h is:
SA = 2πr² + 2πrh = π(2r² + 2rh)
We have:
SA = 126π ft²
h = 3 * d
d = 2r
h = 3 * 2r = 6r
126π = π(2r² + 2rh)
126 = 2r² + 2rh
126 = 2r² + 2r * 6r
126 = 2r² + 12r²
126 = 14r²
r² = 126/14
r² = 9
r = √9
r = 3
The answer to your problem is: 122.32
