Question

The radius of the base of a cylinder is 38 mm and its height is 51 mm. Find the surface area of the cylinder in terms of π.

Answer 1

Answer:

$6764\pi$

Step-by-step explanation:

3876$\pi$

Step-by-step explanation:

The Surface area of the Cylinder is given by the formula

$SA=2\pi r^2+2\pi rh$

Here we are given with the value of radius and the height as 38 mm and 51 mm.  

Now we put the values of r and h in the above formula and evaluate he Surface Area

$SA= 2\pi*38^{2}+2\pi*38*51\\SA=2888\pi+2\pi*1938\\SA=2888\pi+3876\pi\\6764\pi$

Hence the Surface area is

$SA=6764\pi$

Answer 2

C 6764
You need to find the total surface area which is 21249.73271
Then times each option (a,b,c,d) by pi to see if you get 21249.7321
