Question

the height of the cone whose base radius is 5cm and volume is 50pi cm square is 5cm.find true or false​

Answer 1

Answer:

The curved surface area of a cone is πrl, where r is the radius and l is slant height

We need to calculate slant height, it can be done by using the formula l

2

=r

2

+h

2

, where h is height.

So, l

=

r

2

+h

2

=

5

2

+12

2

=13

We have curved surface area of a cone is πrl =π×5×13 =65π cm

2

Hence, the answer is 65π cm

Answer 2

Answer:

the answer will be false.
