Question

the volime of the cylinderical can is 1.54 liters if the height is 20cm find the area of its base​

Answer 1

Answer:

Base Area = 77 cm²

Step-by-step explanation:

We are given,

Volume of Cylinder = 1.54 litres

We know that,

1 L = 1000cm³

1.54 L = 1.54 × 1000 cm³

1.54 L = 1540cm³

We are also given,

h = 20 cm

Now, we know that,

Volume of Cylinder = πr²h

But V = 1540 cm³

Thus,

1540 = πr²(20)

πr² = 1540/20

πr² = 77 cm²

Now, what is πr², it is nothing but the base area.

Area of Circle/base = πr²

Thus,

Base Area = 77 cm²

Hope it helped and believing you understood it........All the best
