The circumference of a circle is equal to C=2πr

From the question, we have 615.44.

Assume that pi is equal to 3.14

Substitute and solve for r

615.44= 2(3.14)r

r= 615.44/ 6.28

r=98.4704

r=98

Therefore, the radius is about 98 units.

To check:

C=2πr

C=2 x 3.14 x 98

C=6.28 x98

C=615.44

A circle in the xy-plane has its center at the point (-6,1). If the point (7, 12) lies on the circle,

Delicious77 [7]

Answer:

radius ≈ 17.0 units

Step-by-step explanation:

The radius is the distance from the centre of the circle to a point on it.

Calculate the radius r using the distance formula

r = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (7, 12)

r = $\sqrt{(7+6)^2+(12-1)^2}$

= $\sqrt{13^2+11^2}$

= $\sqrt{169+121}$

= $\sqrt{290}$ ≈ 17.0 ( to the nearest tenth )
