Formula

2*(L + W) = L * W

Given

W = 3

Solution

2*(L + 3) = 3*L

2L+ 6 = 3L                      Subtract 2L from both sides

2L - 2L + 6 = 3L - 2L      combine

6 = L

Answer: The length is 6 units long.

A circle with radius of 6cm sits inside a circle with radius of 9 cm
san4es73 [151]

Answer: area of shaded region is 141.3 cm²

Step-by-step explanation:

We would assume that the shade region is the area between both circles. The area of the shaded region is the area of the outer circle - the area of the inner circle.

The formula for determining the area of a circle is expressed as

Area = πr²

Where

r represents the radius of the circle.

π is a constant whose value is 3.14

Considering the inner circle,

Radius = 6 cm

Area = 3.14 × 6² = 113.04 cm²

Considering the outer circle,

Radius = 9 cm

Area = 3.14 × 9² = 254.34 cm²

Area of the shaded region is

254.34 - 113.04 = 141.3 cm²

almond37 [142]
The rate that Marcus works is  (1/3) of the job in (4/5) of an hour....

(1/3)/(4/5)=1/h

(1/3)(5/4)=1/h

5/12=1/h

5h=12

h=12/5

So Marcus will take 12/5 hours to complete the job.
