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,

Correct Answer: 62.35

Solution : Given: The side of an equilateral triangle is $12 \text{ cm}$.
Area of the equilateral triangle:
$=\frac{\sqrt{3}}{4} × (\text{side})^{2}$
$=\frac{\sqrt{3}}{4} × 12^{2}$
$=\frac{\sqrt{3}}{4} × 144$
$=\sqrt{3} × 36$
$= 1.732 × 36 $
$= 62.35 \text{ cm}^2$
Hence, the correct answer is 62.35.

Correct Answer: $1:2:3$

Solution : Given: $(2x - y)^2 + (3y - 2z)^2 = 0$
If the sum of squares of two terms is equal to zero, then the individual terms will also be zero.
Since, $(2x - y)^2 + (3y - 2z)^2 = 0$
$\therefore$ $2x - y =
