Question

Calculate the diameter of a solid cylinder which has a height of 72.0cm and a total surface area of 1.5m2.

Answer 1

Answer:

TSA = 1.5 m^2 (GIVEN)

1.5*100= 150

FORMULA OF TSA OF CYLINDER = 2*TT*R*H

HEIGHT = 72 cm

2*3.14*R*72 = 150

R= 150/(2*3.14*72)

 = 150/(6.28*72)

 =150/452.16 =15000/45216= 0.3 cm

D= 2*R

 2*0.3=0.6 cm
