Answer 2

Hello, Buddy!!

➸ GIVEN:

• Diameter of the base of a cone is 10.5cm.
• Slant height of the cone is 10cm.

➸ TO FIND:

• Curved Surface Area of the Cone.

➸ Required Response:

Radius of the cone

→ 10.5/2

→ 5.25

• Radius = 5.25cm

Curved Surface Area of the Cone

$\mapsto \: {\pi}rs \\ \mapsto \: 3.14 \times 5.25 \times 10 \\ \mapsto \: 3.14 \times 52.5 \\ \mapsto \: 164.85$

Curved Surface Area of the Cone

• $\longmapsto\;\red{\bold{164.85{cm}^{2}}}$

☛ Formulas Used:

$\boxed{\sf{Radius = \frac{Diameter (d)}{2}}}$

$\boxed{\sf{{Surface\;Area\;of\;Cone}_{[Curved]} = {\pi}rs}}$

Where, 'r' is Radius & 's' is Slant Height

$\boxed{\tt{@MrSovereign}}$
