Answer 1

the volume should be 140 cm.

Answer 2

Step-by-step explanation:

given

the radius of cylinder=7cm

the hieght of cyclinder=20cm

so,

volume of CYCLINDER=πr^2h

$= \frac{22}{7} \times {7}^{2} \times 20 \\ = \frac{22}{7} \times 7 \times 7 \times 20 \\ = 22 \times 7 \times 20 \\ = 440 \times 7 \\ = 3080cm {}^{3}$
