Team Careers360 · Accepted Answer

Correct Answer: 188.57 units

Solution : Radius, $r$ = 6 units
Height, $h$ = 8 units
Let the slant height be $l$.
So, $l^2= {r^2+h^2}= \sqrt{6^2+8^2}= \sqrt{100}= 10$ units
Area of the canvas = Curved surface area of cone
= $ \pi r l$
= $\frac{22}{7}×6×10$
= $188.57$ units
Hence, the correct answer is 188.57 units.
