Explanation -:

In this question it is given that the radius of a cylinder is 3 inches. The height of the cylinder is 10 inches. We are asked to calculate the surface area of the cylinder in terms of π .

Radius = 3 inches

Height = 10 inches

We know,


\star \: \small \boxed{\rm{ Surface \: area \: of \: a \: cylinder = πr²h}}

Substituting the values we get


\small\sf{ Surface \: area \: of \: a \: cylinder = π × 3² × 10}


\small\rm{ Surface \: area \: of \: a \: cylinder = π × 3 * 3 × 10}


\small\rm Surface \: area \: of \: a \: cylinder = π × 90


\small\sf{ Surface \: area \: of \: a \: cylinder = \bf{90 π \: inches²}}

Answer:

90π in²

Explanation:

Surface area of cylinder:

r = 3 in

h = 10 in


\sf \boxed{\text{\bf Surface area of cylinder =$\pi r^2h$}}


= \pi 3*3*10\\\\= 90 \pi \ in^2
