Yes because they go up by 2
Answer:
66π in²
Step-by-step explanation:
Area of one circular base: πr² ⇒ π3² ⇒ 9π
Area of the two circles: 9π + 9π = 18π
We know that the length of the rectangle is 8 in, but we still have to find width. The width of the rectangle is the circumference of either circle:
Width of rectangle: 2πr ⇒ 2π3 ⇒ 6π
Area of rectangle: 6π · 8 = 48π
Total Surface Area: 48π + 18π = 66π in²
Total Surface Area (using the π symbol on a calculator)≈ 207.345 in²
Hopefully this helps!
Answer: Range is something
Step-by-step explanation:
P = 2(L + W)
P = 36
36 = 2(L + W)
36/2 = L + W
18 = L + W....L = 18 - W
A = L * W
A = 65
L = 18 - W
65 = W(18 - W)
65 = 18W - W^2
W^2 - 18W + 65 = 0
(W - 13)(W - 5) = 0
W - 13 = 0 .....L = 18 - 13
W = 13 L = 5
W - 5 = 0 L = 18 - 5
W = 5 L = 13
Not exactly sure which (length or width)...but one is 13 ft and the other is 5 ft
