{\huge{\red{\underline{\overline{\mathit{\red{ANSWER↓}}}}}}}

\therefore Diameter of the base = 10.5cm

\therefore Radius of the base(r) = \large\dfrac{10.5}{2} cm

= 5.25cm

Slant height (l)=10cm

\therefore Curved surface area of the cone = πrl

= \large\dfrac{22}{7} × 5.25×10

= {\large{\boxed{\sf{165cm²}}}}
