Answer pls . Hurry up guys

Answer 1

Step-by-step explanation:

given

TSA=968cm^2

radius =7cm

height =? h(let)

$total \: surface \: area \: of \: cylinder \\ = 2\pi \: r(r + h)$

=2πr^2+2πrh=968

=2π49+2πrh =968

2πrh=968-2π49

2πrh=968-308

$h = \frac{968 - 308}{2 \times \frac{22}{7} \times 7} \\ h = \frac{660}{44} = \frac{330}{22 } = \frac{30}{2} = 15cm$

hence the height of cylinder is 15cm
