Question

The volume of open cylindrical can is 6358cm3 and its height is 28cm .Find its radius and curved surface area

Answer 1

Answer:

6358=1/3* pi*r^2* h

6358=1/3*3.14*r^2*28

6358*3/3.14*28 = 216.9

216.9=r^2

sq rt{216.9}=r

r = 14.7

Step-by-step explanation:

then later on csa =2*pi*r^2

2*3.14*14.7*14.7=1357.04
