[tex]r = 0.5 yards[/tex] and [tex]Diameter = 1 yards[/tex] .
Step-by-step explanation:
Here we have , Find the radius and the diameter to the nearest hundredth when C = π yd. Use 3.14 for π. let's find out:
We know that circumference of circle = [tex]2\pi r[/tex]
According to question ,
[tex]Circumference = \pi[/tex] So ,
⇒ [tex]2\pi r = Circumference[/tex]
⇒ [tex]2\pi r = \pi[/tex]
⇒ [tex]\frac{2\pi }{2 \pi}r = \frac{\pi}{2 \pi}[/tex]
⇒ [tex]r = \frac{1}{2}[/tex]
⇒ [tex]r = 0.5 yards[/tex]
We know that , [tex]Diameter = 2(radius)[/tex]
⇒ [tex]Diameter = 2(0.5)yards[/tex]
⇒ [tex]Diameter = 1 yards[/tex]
Therefore , [tex]r = 0.5 yards[/tex] and [tex]Diameter = 1 yards[/tex] .
Answer:
Step-by-step explanation:
Use the formula.
C = πd
1π = πd Substitute 1π for C.
1π
π = πd
π
Divide both sides by π.
1 = d Simplify.
Use the formula.
d = 2r The diameter of a circle is the same as 2 times the radius.
1 = 2r The diameter is 1. Substitute 1 for d.
1/ 2 = 2r/ 2
Divide both sides by two.
0.5 = r
The diameter is 1 yard.
The radius is 0.5 yards.
