Question

a cyclinder has radium 2.1 m and height 9 cm . it volume is​

Answer 1

Answer:

vol=1.2474 m³

Step-by-step explanation:

vol= π r²h

    = (22/ 7 )×2.1×2.1×0.09 (9 cm =9/100=0.09m)

   =1.2474 m³

Answer 2

Step-by-step explanation:

Radius =2.1 m

height =9 m

1. Formula:

• $\pi \: r { \: }^{2} h$
• substituting the values
• volume =3.142 .(2.1)^2*9
• =3.142 *4 .41*9
• 124.705 sq m
