WOW!! The same answer for both!!! Does it always happen? No!! Only in special cases. But let us get some experience. a. h=5 ft, r= 2 ft b. h=4 m, r = 6 m C. r=5 cm, h = 10 cm d. h = 9 in, d = 6 in (Be Careful!!)

Here, we want to get the volume and the surface area of the right cylinder

From the question, we have the height as 5 ft and radius as 2 ft

Mathematically, we have the calculations as follows;

a)


\begin{gathered} S\mathrm{}A\text{ = 2}\pi r(r\text{ + h)} \\ =\text{ 4}\pi(5+2)=87.965ft^2 \end{gathered}

b)


\text{Volume = }\pi* r^2* h\text{ = }\pi*2^2*5=62.832ft^3

In each of the solutions above, the value used for pi is 22/7
