Question

find the height of a cylinder whose diameter is 14m and the total surface area is 968m²​

Answer 1

Answer:

Diameter-14m

surface area-968

by using formula-

$a = 2\pi \: d \div 2 + 2\pi(d \div 2) {}^{2}$

h=4

Answer 2

Height =15m

Step-by-step explanation:

total surface area of a cylinder =968m^2

t.s.a=2*pie*r(r+h)

=2×22/7×7(7+h)=968

=44(7+h)=968

=7+x=968/44=22

x=22-7

=15

height =15m
