Question

Surface area of a cylinder with a radius of 7cm and a height of 12​

Answer 1

Answer:

CSA = 2 * pi * r * h

Step-by-step explanation:

CSA = 2 * 22 * 7 * 12 / 7

= 2 * 22 * 12

528 cm ^3

$To~find~the~surface~of~a~cylinder,~we~use~the~formula~that~is:$

$\boxed{~A=2\pi r ~h+2\pi r^2~}$

$In~our~case~we~have:$

$=2\times \pi \times 7\times 12+2\times \pi \times 7^2$

$=835.66cm^2$

$Thus,~the~surface~area~of~this~cylinder~is~835.66cm^2.$

$Hope~this~helps~and~have~an~amazing~day~ahead!$
