A frustum-shaped bucket of radii 21 cm and 14 cm and height 24 cm is to be made of metal sheet. Find the curved surface area only, in cm^2 (use π = 22/7). (First find slant height = √24^2 + 7^2.)

Question

Accepted Answer

2750. l = √576 + 49 = √625 = 25 cm. CSA = 22/7*25*(21 + 14) = 22/7*25*35 = 22*25*5 = 2750 cm^2.

A frustum-shaped bucket of radii 21 cm and 14 cm and height 24 cm is to be made of metal sheet.
Find the curved surface area only, in $cm^{2}$ (use π = $\frac{22}{7}$ ). (First find slant height = $2 4^{2} + 7^{2} .$ )
