Question

4. If the curved surface area of 2 points
a cylinder is 1760 sq. cm. and
base radius is 14 cm. Then, find
its height. *
O 20 cm

80 cm
14 cm​

Answer 1

Answer:

Given, curved surface varea of cone =1760 sq.cm and radius =14 cm

We know, curved surface area of a cylinder of radius "R" and height "h" =2πRh

Hence, curved surface area of the given cylinder =2×

22

×14×h=1760sq.cm

∴h=20 cm
