Answer:

28.2743 square feet (28 square feet, rounded)

Step-by-step explanation:

The area of a circle is given by the equation

Area = πr^2

Plug in 3 for the radius

Area= π(3)^2

3 squared is 9

Area= 9 π

Area= 28.2743 square feet

Rounded to the nearest square foot, the area of the circle is 28 square feet.

Find the cost of carpeting a room 3.6m high at Rs 120 per square meter if it contains 240 mcube of air
NeX [460]

Answer:

Rs 8000

Step-by-step explanation:

Volume = Base area × Height

If we want to find the cost of carpeting a room, we need to find how much space there is to carpet, which would be the base area of the room.

240m³ = Base area × 3.6m

Base area = 240m³ ÷ 3.6m

Base area = 66\frac{2}{3}m²

1m² --- Rs 120

66\frac{2}{3}m² --- 66\frac{2}{3} × Rs 120 = Rs 8000

What is 3 1/4 divided by 2/3 with all of the steps?
erik [133]

Answer:

4 7/8

Step-by-step explanation:

3 1/4 / 2/3

convert mixed numbers to improper fractions: 3 1/4 / 2/3

13/4 / 2/3

apply the fraction rule: a/b / c/d = a/b * d/c

= 13/4 * 3/2

multiply fractions: a/b * c/d = (a * c)/(b * d)

= (13 * 3)/(4 * 2)

multiply the numbers: 13 * 3 = 39

= 39/(4 * 2)

multiply the numbers: 4 * 2 = 8

= 39/8

convert improper fractions to mixed numbers: 39/8 = 4 7/8

= 4 7/8
