Formula
------------------------------------------------------
Circumference = πD
------------------------------------------------------
Find Diameter
------------------------------------------------------
10π = πD
D = 10 ← divide by π on both sides
------------------------------------------------------
Find Radius
------------------------------------------------------
Radius = Diameter ÷ 2
Radius = 10 ÷ 2
Radius = 5
------------------------------------------------------
Answer: Radius = 5 units

Step-by-step explanation:
CDE = 2x, DEF = x
hexagon = 720°
720 = 115 + 145 + 160 + 90 + 2x + x
720 = 3x + 510
720 - 510 = 3x
210 = 3x
x = 210 ÷ 3
x = 70°
CDE = 2x
= 2(70)
= 140°
1 notebook costs $3.45
let's turn this into 2 equations, n being notebook price, and b being binder price ->
mandy -> 3n + b = 5.85
jordan -> 2n + b = 4.65
we need to take one equation, simplify for b, and plug it into the other equation, let's take jordan's equation for this ->
b = 4.65 - 2n
plug it into mandy's equation
3n + (4.65 - 2n) = 5.85
simpify until you get n = 1.20
take this and plug it back into jordan's equation ->
2(1.20) + b = 4.65
simplify until you get b = 2.25
plus this value into mnady's equation ->
3n + (2.25) = 5.85
simplify until you get that n = 2.25
Answer: 10 pans
Step-by-step explanation:
<u>Step 1:</u>
If the number of biscuits needed= 80
<u>Step 2:</u>
And the number of biscuits on each pan= 8
<u>Step 3:</u>
Then the number of pans needed= 80 ÷ 8
Answer: 80 ÷ 8 = 10pans
Answer:
Approximately 50.26
Step-by-step explanation:
To find circumference you have to do 2pi x r. We know that the radius of a diameter of 16 is 8, so we'll do 2pi x 8, which is approximately <u>50.26.</u>
