Answer:
Second option: Surface area = 176*pi cm2
Step-by-step explanation:
The surface area of a cylinder is given by:
S = 2*pi*r^2 + 2*pi*r*h
Where r is the base radius and h is the height.
If we have that the diameter is 8 centimeters, the radius is 8/2 = 4 centimeters. So with r = 4 and h = 18, we have that the surface area is:
S = 2*pi*4^2 + 2*pi*4*18 = 176*pi cm2
So the answer is the second option.
We first find out the amount in dollars of interest accrued after 2 years time.
Interest = Prt
where P is the principal, r is the rate and t is time
8% written in decimal fraction → 8/100 → 0.08
Interest = 17000 × 8% × 2
Interest = 1700 × 0.08 × 2
Interest = 2,720 dollars
We add the principal and the interest to get full amount paid, so:
17000 + 2,720 = 19,720
I hope that you good day
It's 67/100 because a percent is out of 100 which is already simplified
