Hi there,
Here is the formula that you need to use to solve for the circumference and the area of a circle.
[tex]C = \pi d= 2\pi r \\A = \pi r^{2}[/tex]
So in this case, [tex]r[/tex] is the radius of the circle
Thus,
[tex]d = 2 == > r = \frac{2}{2} = 1\\C = 2\pi * 1 = 2\pi[/tex]
Now we do the math, to get to:
[tex]C = 6.28[/tex] (approximately, and you only need to keep it to 2 decimal places)
So 6.28 is the circumference, but now we need to find the Area
[tex]A = \pi * 1^2 = \pi[/tex]
So Area = 3.14 (approximately, to 2 decimal places)
Thus the answers are:
The circumference is 6.28 yards and the Area is 3.14 Square years
Please 5 stars and a like if you find this answer helpful.
Happy to help!
Answer:
c = 6.28
a = 1.34
Step-by-step explanation:
If the diameter is 2 yds., then the radius is 1 yd.
Circumference:
c = [tex]\pi d[/tex]
c = [tex]\pi 2\\[/tex]
c = 6.28 Rounded to the hundredths place
Area:
a = [tex]\pi r^{2}[/tex]
a = [tex]\pi 1^{2}[/tex]
a = [tex]\pi 1[/tex]
a = 3.14 Rounded to the hundredths place
