-.From a solid right circular cylinder with height 12 cm and radius of the base 5cm,
a right circular cone of the same base radius is removed. Find the volume and total
surface area of the remaining solid. (π= 22/7)
Answers
Answer:
Step-by-step explanation:
volume of the cone=1/3 * 22/7 * 5^2 * 12
=314.29 cm^3
volume of the cylinder=22/7 * 5^2 * 12
=942.86 cm^3
volume of the remaining solid=942.86-314.29
=628.57 cm ^3
total surface area of the remaining solid=22/7 * 5^2 + 2 * 22/7 * 5 * 12 + 22/7 * 5 * (5^2+12^2)^1/2
=78.57+377.14+204.29
=660 cm^2
