Question

Find Total surface area of a cylender whole Height is 6m and diameter is 3m​

Answer 1

Question-

Find Total surface area of a cylinder whole Height is 6m and diameter is 3m​

Answer-

Total surface area of a cylinder = 2πr(h + r)

Radius = Diameter/2 = 3/2 = 1.5

Now,

2πr(h + r)

= πd(h + r)

= 3π(6 + 1.5)

= 3π(7.5)

= 22.5π cm²

Answer 2

Answer:

564 \ 7

Step-by-step explanation:

2πr( h+r)

2×22/7×3/2×3/2 ( 6+3)
