Question

curved surface area of cylinder is 1980 CM square and its radius of its base is 15 cm find the height of the cylinder

Answer 1

Answer:

21 CM

Step-by-step explanation:

RADIUS = 15 CM

CSA OF CYLINDER = 2πRH

1980 = 2 × 22/7 × 15 × H

21 CM = H

Answer 2

CSA=1980cm sq
Base=15cm
CSA=22/7×15×15×h=1980
=22/7×15×h=1980
1980×7/22×15=0
1980×7/330=0
=42=h
