Question

A dosed metallie cylinder has its base diameter 56 em and is 2.25 mg
the cost of the metal used to make it wit costs' 6 per ​

Answer 1

Step-by-step explanation:

Radius=Diameter/2=56/2cm=28cm

Height=2.25m

We have to convert radius in m

Therefore, 28/100m=0.28m

T.S.A=2πr (r+h)=2*22/7*0.28*(0.28+2.25)=1.76*2.53m^2=4.4528m^2

Cost of metal=$(4.4528*80)=$356.22
