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
Answer:
A.
Step-by-step explanation:
Plugging in all the values into the equation, only A holds a true statement.
Answer: 10/24
Hope that help :)
You have a base that is 8x8 and the slant height of the triangle is 22.
This is the formula, L=1/2Ph
H = 22 Meters
1. P=2L+2W -> 2(8)+2(8) = 32 meters
2. L= 1/2(32)(22) = 352 meters squared :)
Answer:
The following shape is not a rectangle, but a square. I know this because the length and width are the same amount of square inch(feet, what ever the square counts for on your graph.) and rectangles width are typically longer than their length. However a square shares the same length and width,
Step-by-step explanation:
