Question

find the volume of right circular cone with 1) radius 6cm hight 7cm( 2) radius 3. 5cm hight 12 cm​

Answer 1

Given :

• Height of right circular cone = 7cm
• Radius of right circular cone = 6cm

To find :

Volume of given right circular cone

Formula used :

Volume of right circular cone = (1/3) π r² h

Solution :

$\sf \implies \: Volume \: = \: \dfrac{1}{3} \times \pi \times {(6 \: cm)}^{2} \times (7cm) \\ \\ \sf \implies \: Volume \: = \dfrac{1}{3} \times \dfrac{22}{7} \times 36 \times 7 \: {cm}^{3} \\ \\ \sf \implies \: Volume \: = 22 \times \dfrac{7}{7} \times \dfrac{36}{3} {cm}^{3} \\ \\ \sf \implies \: Volume \: = \: 22 \times 1 \times 12 \: {cm}^{3} \\ \\ \sf \implies \: Volume \: = \: \bold{ 264 \: {cm}^{3} }$

ANSWER :

Volume of given right circular cone = 264 cm³
