Answer:

(x-1) ^2 + (y+4)^2 = 4

Step-by-step explanation:

The equation of a circle can be written as

(x-h) ^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius

(x-1) ^2 + (y- -4)^2 = 2^2

(x-1) ^2 + (y+4)^2 = 4

Find the radius and the diameter to the nearest hundredth when C = π yd. Use 3.14 for π.

STALIN [3.7K]

$r = 0.5 yards$ and $Diameter = 1 yards$ .

<u>Step-by-step explanation:</u>

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 = $2\pi r$

According to question ,

$Circumference = \pi$ So ,

⇒ $2\pi r = Circumference$

⇒ $2\pi r = \pi$

⇒ $\frac{2\pi }{2 \pi}r = \frac{\pi}{2 \pi}$

⇒ $r = \frac{1}{2}$

⇒ $r = 0.5 yards$

We know that , $Diameter = 2(radius)$

⇒ $Diameter = 2(0.5)yards$

⇒ $Diameter = 1 yards$

Therefore , $r = 0.5 yards$ and $Diameter = 1 yards$ .
