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 .
