Question

-
A bucket open at the top has top and bottom radii of circular ends as
40 cm and 20 cm respectively. Find the volume of the bucket if its depth
is 21 cm. Also find the area of the tin sheet required for making the
bucket(22/7)​

Answer 1

Answer:

Hope it helps you.

Step-by-step explanation:

Answer 2

Answer:

Volume = 61,600 cm³

Step-by-step explanation:

Given:

Radius (r1) = 40 cm

Radius (r2) = 20 cm

Height (h) = 21 cm

Find:

Volume

Area of sheet

Computation:

Volume = (1/3)πh[r1² + r2² + (r1 × r2)]

Volume = (1/3)(22/7)(21)[40² + 20² + (40 × 20)]

Volume = 22[1,600 + 400 + 800]

Volume = 22[2,800]

Volume = 61,600 cm³
