Question

The total surface area of cylindrical can whose height is equal to the radius of the base is 2464cm square find its volume ​

Answer 1

Let the radius of the cylinder be x therefore the height of the cylinder is also x.

TSA of the cylinder =2464 cm

2

2πr(h+r)=2464 cm

2

2×22/7×x(x+x)=2464 cm

2

44/7×x(2x)=2464cm

2

44/7×2x
