Question

find the volume of right circular cone with radius 2.8 centimetre height 12 CM
​

Answer 1

Answer:

98.56 cm³

Step-by-step explanation:

Volume of Cone = 1÷3 πr²h

Placing the values in the formula we get,

1/3 × 22/7 × (2.8)² × 12 = 98.56 cm³

Answer 2

GiveN :-

• Radius of cone = 2.8 cm

• Height of cone = 12 cm

To FinD :-

• Volume of the cone

SolutioN :-

$\large\longrightarrow \boxed{ \green{ \sf Volume_{cone} = \frac{1}{3}\pi {r}^{2} h}} \\ \\ \longrightarrow \sf \frac{1}{3} \times \frac{22}{7} \times \frac{28}{10} \times \frac{28}{10} \times 12 \\ \\ \longrightarrow \sf\frac{1}{1} \times \frac{11}{1} \times \frac{14}{5} \times \frac{4}{5} \times 4 \\ \\ \longrightarrow \sf \frac{2464}{25} \\ \\ \longrightarrow \sf98.56 \: {cm}^{3}$

$\large \red{ \underline{ \bf \therefore Volume \: of \: cone \: is \: 98.56 \: {cm}^{3}}}$
