P(mm) = 40/100 x 40/100 = 4/25
p(ff) = 60/100 x 60/100 = 9 /25
4/25 + 9/25
= 13/25
Answer:
![SA=62.8\ ft^2](https://tex.z-dn.net/?f=SA%3D62.8%5C%20ft%5E2)
Step-by-step explanation:
we know that
The surface area of a cylinder is equal to
![SA=2\pi r^{2}+2\pi rh](https://tex.z-dn.net/?f=SA%3D2%5Cpi%20r%5E%7B2%7D%2B2%5Cpi%20rh)
we have
![h=3\ ft](https://tex.z-dn.net/?f=h%3D3%5C%20ft)
----> the radius is half the diameter
assume
![\pi =3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D3.14)
substitute
![SA=2(3.14)(2)^{2}+2(3.14)(2)(3)](https://tex.z-dn.net/?f=SA%3D2%283.14%29%282%29%5E%7B2%7D%2B2%283.14%29%282%29%283%29)
![SA=62.8\ ft^2](https://tex.z-dn.net/?f=SA%3D62.8%5C%20ft%5E2)

Answer:5 h 48 min
Step-by-step explanation:
t/8+t/12=1
=> 3t+2t =24
5t=24
t=24/5
t=5 and 4/5 h
That equal to 5 h and 8/10 h or 5h and 8*6 min
So the answer is 5 h 48 min
