Answer:
37%
Step-by-step explanation:
Surface area of a cylinder = πr² + 2πrh
With r = 22 and h = (6 + 10) = 16
Area = π * 22² + 2 * π * 22 * 16
Area = 1520.728 + 2211.968
Area = 3732.696 in²
Percentage of green = surface area of green ÷ total surface area
Surface area of green = 2πrh
Surface area of green = 2 * π * 22 * 10
Surface area of green = 1382.48
Percentage of green = 1382.48 / 3732.696 * 100%
Percentage of green = 37%
Answer:
x=-10/23
Step-by-step explanation:
-23x=10
x=10/-23
x=-10/23
Step-by-step explanation:
in a geometric sequence there is a constant factor x that is multiplied with every previous term to create the next one.
a2 = 20
a5 = 1280 = a2×x×x×x = a2×x³ = 20x³
64 = x³
x = 4
=> a1 = 5
therefore
an = an-1×4 =
n > 1
