Question

The Curved surface area of a Cone is 550 cm2 and its diameter is 14 cm. what is its height?​

Answer 1

Answer: 25cm

Step-by-step explanation:

Curved surface area of cone is pi x r x l

Therefore 22/7*7*x = 550

x=550/22

x= 25cm

Answer 2

Answer:

Height is 24 cm

Step-by-step explanation:

diameter=14cm

Radius=7cm

CSA=πrl

550cm^2=(22/7) ×7×l

(550×7) /(22×7) =l

25cm=l

l^2=r^2+h^2

25^2=7^2+h^2

625=49+h^2

625-49=h^2

576=h^2

√576=h

24 cm= height
