Question

In a school, exactly at the middle of the stage of the assembly hall, after drawing a circle of 2.8 in radius, a beautiful picture is to draw in it. Cost for drawing is Rs.300 per 1 sq m. What is the total cost of drawing a picture in this circle?

Answer 1

Answer:

₹7272..............

Answer 2

Answer:

Rs 7386

Step-by-step explanation:

Since the circle is of radius (r) = 2.8 m.

We have to first calculate the area of the circle;

∴ So, the area of the circle will be (A) = π$radius^{2}$

A = $3.14 \times 2.8^{2}$

So, A = 24.62 sq m

Now according to the question, a design is to be inserted inside the circle.

Since the cost per 1 sq m is Rs 300

Now , we have to calculate the whole cost for inserting a design.

∴ The total cost will be Rs  $300 \times 24.62$

= Rs 7386

∴ The total cost will be Rs 7386
