Calculate the volume of a right circular cone having base radius 6 cm and vertical height 7 cm. (Take pi = 22/7)
Answer and explanation
Correct answer: B. 264 cm^3
- Step 1: Volume formula of a cone: Volume = (1 / 3) pi r^2 h. Step 2. Substitute values: Volume = (1 / 3) (22 / 7) 6^2 7 = (1 / 3) (22 / 7) 36 7 = (1 / 3) 22 36 = 22 12 = 264 cm^3. Answer: 264 cm^3. Why not the others: 792 cm^3 forgets the 1/3 factor (cylinder volume); 132 cm^3 halves the volume; 528 cm^3 doubles it.
