Find the slant height of a cone whose volume is 1232 cm³ and radius of the base is 7 cm.
A25 cm
B12 cm
C32 cm
D18 cm
Answer:
A. 25 cm
Read Explanation:
• Volume of the cone =(1/3)πr²h = 1232
• h = 1232x3 /πr²= (1232*3*7)/(22*7*7)
• Slant height l is given by the relation
I = square root of (h²+r²)
= square root of (24²+7²)
= square root of (625)
=25 cm
• Slant height of the cone is 25 cm
