115.5cm
Correct answer is C
Perimeter of a sector = \(2r + \frac{\theta}{360} \times 2\pi r\)
= \(2(10.5) + \frac{120}{360} \times 2 \times \frac{22}{7} \times 10.5\)
= \(21 + 22\)
= 43 cm

12cm
15cm
Correct answer is C
Area of rhombus = \(\frac{pq}{2}\)
where p and q are the two diagonals of the rhombus.
\(\therefore 60 = \frac{12 \times q}{2}\)
6q = 60 \(\implies\) q = 10 cm

Correct answer is C
Volume of a cone = \(\frac{1}{3} \pi r^2 h\)
r = 4\(\frac{1}{2}\) cm; h = 14 cm
Volume of cone = \(\frac{1}{3} \times \frac{22}{7} \times \frac{9}{2} \times \frac{9}{2} \times 14\)
= 297 cm\(^3\)
When half- filled, the volume of the water = \(\frac{297}{2} = 148.5 cm^3\)
Calculate the total surface area of a cone of height 12cm and base radius 5cm. [Take π = 22/7]
