Question

the volume of a cone of height 5 cm is 753.6 cm cube this cone and cylinder has equal radii and height find TSA of cylinder​

Answer 1

Answer:

GIVEN: volume of a cone =753.6cmcube

height of a cone =5cm

a cylinder also has the equal radii and height

TO FIND: TSA of a cylinder

SOLUTION:

Volume of a cone =1÷3×πr×r×h

753.6 =1÷3×3.14×r×r×5

753.6×3 =r×r

___________

3.14×5

144 = rr

TAKING SQUARE ROOTS

r =12

TSA of cylinder =2πr(r+h)

=2×3.14×12(12+5)

=75.36(17)

=1281.12
