The volume formula of a cylinder is given as:
V = π r^2 h
So plugging in the value of the volume:
10 ft^3 = π r^2 h
<span>h = 10 / (π r^2) --->
eqtn 1</span>
The formula for the surface area of cylinder is:
s = 2 π r h + 2 π r^2
plugging in eqtn 1:
s = 2 π r [10 / (π r^2)] + 2 π r^2
<span>s = (20 / r) + 2 π r^2 (ANSWER)</span>
Yes, 14 is correct.
15: 3^4 - 4
16: 7n - 6
17: n^2 / 8
18: 3n x 9
Answer:
addition because it's in parentheses and following PEMDAS parentheses comes first so you do addition first.
I hope you find this helpful :D
Answer:
65.8
Step-by-step explanation:
(2.6*4.7)/2=6.11
11*4.7=51.7
(4.7(17-(2.6+11)))/2=7.99
6.11+51.7+7.99=65.8
F,e and h,i are vertical angles i think.
