a) 3846.5 cm^{2}

b) 1052 cm^{2}

c) 1153.4 cm^{2}

d) 3172 cm^{2}

View Answer

Explanation: Slant height = \(\sqrt {h^2+r^2}\)

c) \(\frac {1}{2}\)πr^{2}h

d) \(\frac {1}{2}\)πr^{3}h

View Answer

Explanation: Volume of right circular cone = \(\frac {1}{3}\)πr

^{2}h

Where ‘r’ is the radius of the base and ‘h’ is the height of the right circular cone.

5. What is the formula for the curved surface area of a rectangular circular cylinder?

a) 2πr^{2}h

b) 2πrh

c) 2π(r + h)

d) 2π(rh)

View Answer

Explanation: The curved surface area of a rectangular circular cylinder = 2πrh

Where ‘r’ is the radius of the base and ‘h’ is the height of the right circular cylinder.

6. What is the total surface area of an iron sphere having a radius of 11 cm?

a) 1529.76 cm^{2}

b) 1514.76 cm^{2}

c) 1519.76 cm^{2}

d) 1419.76 cm^{2}

View Answer

Explanation: The total surface area of an iron sphere = 4πr

^{2}

= 4 × \(\frac {22}{7}\) × 11

^{2}

= 1519.76 cm

^{2}

7. What is the volume of a hemisphere if the radius of the hemisphere is 3 m?

a) 135.4 m^{3}

b) 56.52 m^{3}

c) 120.23 m^{3}

d) 105.5 m^{3}

View Answer

Explanation: Radius of the hemisphere = \(\frac {2}{3}\)πr

^{3}

= \(\frac {2}{3}\) × 3.14 × 3

^{3}

= 56.52 m

^{3}

8. Find the slant height of the right circular cone if the base diameter of the right circular cone is 14 cm and the height is 24 cm.

a) 11 cm

b) 13 cm

c) 28 cm

d) 25 cm

View Answer

Explanation: Radius (r) = \(\frac {diameter}{2} = \frac {14}{2}\) = 7 cm

Slant height = \(\sqrt {h^2+r^2}\)

= \(\sqrt {24^2+7^2}\)

= \(\sqrt {576+49}\)

= 25 cm

9. The lateral surface area of a right circular cone is 2020 cm^{2} and its radius is 10 cm. What is its slant height?

a) 28.3 cm

b) 25.6 cm

c) 68.23 cm

d) 64.33 cm

View Answer

Explanation: The lateral surface area of a right circular cone is 2020 cm

^{2}.

πrl = 2020

3.14 × 10 × l = 2020

l = \(\frac {2020}{3.14 \times 10}\)

= 64.33 cm

10. Find the volume of the right prism with an area of base 121 m^{2} and a height of 23 m.

a) 4793 m^{3}

b) 2763 m^{3}

c) 2783 m^{3}

d) 4783 m^{3}

View Answer

Explanation: The volume of the right prism = Area of base × height

= 121 × 23

= 2783 m

^{3}
