  • Answer:

<em>43.96 cm</em>

<em>≈ 44 cm</em>

  • Step-by-step explanation:

<em>Hi !</em>

<em>C₁ = 2π×r₁</em>

<em>C₂ = 2π×r₂</em>

<em>C₂ - C₁ = 2π×r₂ - 2π×r₁</em>

<em>= 2π(23cm - 16cm)</em>

<em>= 2×3.14×7</em>

<em>= 43.96 cm</em>

<em>≈ 44 cm</em>

<em>Good luck !</em>

Answer:

44 cm

Step-by-step explanation:

r = 16,R = 23;2πR - 2πr

2π(R - r)

2 ×22/7(23 -16)

2×22/7×(7)

2×22=44cm...

Find the value of x.<br> I Need to show the equations please, and show my work
defon

Answer:

15

Step-by-step explanation:

since both equations are set with a right angle, the equation must be equal to 90 degrees. So you set the equation as

13+x+4x+2=90

add the x variables together and the constants separately

15+5x=90

then subtract 15 from both sides.

15+5x=90

-15      -15

5x=75

then divide 5 from both sides.

75/5= 15

so x is 15 :).

Jordan is putting a fence around a garden that is shaped like a half circle and rectangle
grin007 [14]

Answer:

92 ft  

Step-by-step explanation:

Assume the garden has the shape shown below.

The length of fencing equals the distance around three sides of the rectangle plus that around the semicircle.

1. Around the rectangle

Distance = 28 ft + 14 ft + 28 ft = 70 ft

2. Around the semicircle

For a circle.

C = 2πr

For the semicircle,

½C =½(2πr) = πr  

D = 14 ft, so

r =    7 ft

\text{Distance} = \dfrac{22}{7} \times \text{7 ft} = \text{22 ft}

3. Total distance

Distance = 70 ft + 22 ft = 92 ft

Jordan will need 92 ft of fencing.
