Directions: Find the area of a circle with given radius. Round off your answer to the nearest hundredths. 1. r= 3.2 m

2. r = 17 mm

3. r = 36.5 mm

4. r = 83 cm

5. r = 5.8 m

A. Find the volume of the following:

Formula: V = e x e x e

6. e = 45.25 cm

7. e = 29 cm

Formula: V = L x W x H

8. l = 23 cm
w= 14 cm
h = 11 cm

9. l = 41 cm
w= 28 cm
h = 17 cm

10. l = 20 cm
w= 18 cm
h = 14 cm

Cost to cover the floor is $196 .

Step-by-step explanation:

Formula

Area of a square = a²

Where a is the side of a square .

As given

The sides of a square bedroom measure 3.5 yards.

Area of a square bedroom = 3.5 × 3.5

                                            = 12.25 square yard .

As given

if carpet costs $16 per square yard .

Cost to cover the floor = Area of a square bedroom × Cost per square yard .

Put all the values in the above

Cost to cover the floor = 12.25 × 16

                                      = $ 196

Therefore  cost to cover the floor is $196 .
