Answer:
Circumference ≅ 195 mm
Step-by-step explanation:
The circumference of a circle is equal to: 
Since 
we can replace that in the circumference equation giving us:
We know Diameter = 622 mm and pi = 3.14 so:
Answer: 47.1/15
Step-by-step explanation:
We define Circumference by C= pie X D[diameter]
Hence pie= C/ D= 47.1/15
Answer:
56 miles
Step-by-step explanation:
(94.50 - 18.50) ÷ f = a
f=family members
a=answer
I don't know how many family members there are, but you would just replace f with the amount.
Answer:
615.44 mm²
Step-by-step explanation:
Before finding the area of the circle, first, let us find the radius of the circle.
Given that,
diameter ⇒ 28 mm
Therefore,
<h3>d = 2r</h3>
28 = 2r
Divide both sides by 2.
14mm = radius
<u> </u>
And now, let us find the area.
The formula to find the area of the circle is :
<h3>Area = π r²</h3>
Let us solve now.
Area = π r²
= 3.14 × 14 × 14
= 43.96 × 14
=<u> 615.44 mm²</u>
