The circumference of a circular rug is 24.8 meters. What is the area of the rug? Use 3.1 for pi
mestny [16]

Answer:

The area of rug is 48.9 m^2

Step-by-step explanation:

Let's assume radius of rug is r m

we know formula for circumference as

C=2\pi r

we are given

C=24.8

and then we can solve for r

24.8=2\pi r

r=3.947

now, we can use area formula

A=\pi r^2

we can plug r

and we get

A=\pi (3.947)^2

A=48.94227

So,

The area of rug is 48.9 m^2

Hasan buys two kinds of cloth materials for school uniforms, shirt material that costs him ₹ 50 per metre and trousers material
True [87]

Answer:

Step-by-step explanation:

Let x represent the number of meters of shirt material that he bought.

Let y represent the number of meters of trouser material that he bought.

For every 3 metres of the shirt material, he buys 2 metres of the trouser material. It means that

2x = 3y

x = 3y/2

shirt material cost him ₹ 50 per metre and trousers material cost him ₹ 90 per metre. It means that the total cost is

50x + 90y

Selling price for the shirt material is

50x + (12/100 × 50x) = 56x

Selling price for the trouser material is

90y + (10/100 × 90y) = 99y

If his total sale is ₹ 36,600, it means that

56x + 99y = 36600- - - - - - - - 1

Substituting x = 3y/2 into equation 1, it becomes

56(3y/2) + 99y = 36600

Multiplying both sides by 2, it becomes

168y + 198y = 73200

366y = 73200

y = 73200/366

y = 200

x = 3y/2 = 3 × 200/2

x = 300

He bought 200 meters of trouser material
