Question

Find the height of the cylinder

Whose radius is 7 cm and the total surface area is 968 cm2

. Also find the volume of the

cylinder.​

Answer 1

Answer

Step-by-step explanation:

we know that the total surface area of the cylinder is = $2\pi r(h+r)$

given that r=7, TSA=968

putting in formula

2 x 22/7 x 7(7+h) = 968

44(7+h) = 968

dividing both sides by 44 we get

7+h = 22

h = 15cm

Volume of cylinder = $\pi r^{2} h$

putting values in formula, we get

volume = 22/7 x 7 x 7 x 15

22 x 7 x 15

= 2310$cm^{3}$

Answer 2

Answer:

Total surface area of a cylinder = 2×22/7×7(7+h)=968cm^2

44(7+h)=968

(7+h)=968/44

h=22-7

h=15cm

volume of the cylinder = 22/7×7×7×15

=2310cm^3
