Question

Find the slant height of a cone whose volume is 1232 cm³ and radius of the base is 7 cm.

• A. 25 cm
• B. 12 cm
• C. 32 cm
• D. 18 cm

Answer 1

Answer:

A. 25 cm

• 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
