Detailed Solution
Download Solution PDFRadii of two circular faces of the frustum of a cone are 5 cm and 3 cm
Height of the circular frustum of cone H = 10.5 cm
As we know,
Volume of the frustum of cone = 1/3 × π [R2 + r2 + Rr] H
⇒ 1/3 × 22/7 × [52 + 32 + 5 × 3] × 10.5
⇒ 11 × [25 + 9 + 15]
⇒ 11 × 49
