Answer 1

C

Explanation:

Answer 2

Answer: C.
`126\pi \text{units}^2`

Explanation:

The surface area of right cylinder is given by :-

`S.A.=2\pi r(r+h)`

Given : Height : h=2 units

Radius : r= 7 units

The the surface area of the given right cylinder will be :-

`S.A.=2(\pi) (7)(2+7)\ \ \ \text{Put }\pi=3.14`

i.e.
`S.A.=126\pi \text{units}^2`

Hence, the surface area of the right cylinder =
`126\pi \text{units}^2`
