Find the volume of a cone of radius 3.5cm and vertical height 12cm. [Take π = 22/7]
15.5cm3
21.0cm3
142cm3
154cm3
Correct answer is D
volume of a cone = ⅓ π r2h → 1∗22∗3.5∗3.5∗123∗7
= 154cm3
5cm
7cm
10cm
15cm
Correct answer is C
Area of a trapezium = [a+b]h2
105 = [9+12]h2 → 105 x 2 =21h
h = 21021 → 10cm
Find the correct to two decimal places, the volume of a sphere whose radius is 3cm. [Take π = 227]
72.57cm3
88.12cm3
10529cm3
113.14cm3
Correct answer is D
Volume of sphere = \(\frac{4πr^3}{3}\) → \(\frac{4 x 22 x 3^3}{3}\)
= 7927
= 113.14cm3
Find the mean
33.35
