Answer:

 4pi

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

where r is the radius

The radius of a circle is found by

r =d/2 where d is the diameter

r = 4/2 = 2

So A = pi (2)^2

        pi (4)

andrey2020 [161]

Answer:

the selling price of the goods is ₹6,00,000

The computation of the selling price of the goods are shown below:

As we know that

Selling price = Cost price + profit

= 5,00,000 + 5,00,000 × 0.20

= 5,00,000 + 1,00,000

= ₹6,00,000

Hence, the selling price of the goods is ₹6,00,000
