Answer:

23.55

Step-by-step explanation:

We know it's three quarters of a circle since the angle is $270$ °

Therefore we can calculate like a normal circle and multiply by $\frac{3}{4}$ .

The formula for calculating the circumference is 2 times pi times the radius or $2\pi r$ .

$\pi=3.14\\2\times\pi=6.28\\6.28\times5=31.4\\31.4\times\frac{3}{4}=23.55$

A rectangular carpet measures 12m by 5m. Part of the carpet is covered by a square rug of length 2m. What fraction of the carpet

guajiro [1.7K]

Answer:

¹/15

Step-by-step explanation:

Area of the rug = s²

Where s = 2 m

Area of the rug = 2² = 4 m²

Area of the rectangular carpet = length × width

Where,

Length = 12 m

Width = 5 m

Area = 12 × 5 = 60 m²

Fraction of the carpet covered by the rug = area of the rug ÷ area of the carpet = 4/60 = ¹/15

horsena [70]

6(2)+3y=15
12+3y=15
-12 -12
3y=3
3y/3 3/3
y=1

6(5)+3y=15
30+3y=15
-30 -30
3y=-15
3y/3 -15/3
y= -5
