Question

Q.7) Find the curved surface area of a right circular cone whose slant height is
10cm and base radius is 7 cm.​

Answer 1

Answer:

The curved surface area of the right circular cone is 220 $cm^{2}$

Step-by-step explanation:

Given -

Slant height = 10cm

Base radius = 7cm

To find -

The curved surface area of a right circular cone.

Solution -

We can follow the given steps to solve this question easily,

Now,

Slant height (l) = 10cm

Base radius (r) = 7cm

C.S.A (curved surface area) of right circular cone = ?

According to what we know,

C.S.A of right circular cone = πrl

                                             =  $\frac{22}{7}$ × 7 × 10

                                             = 220 $cm^{2}$

(This will be the final answer as the area of any shape is in the form of base unit squared, in this case, $cm^{2}$ )

Hence, the curved surface area of the right circular cone will be 220 $cm^{2}$
