Answer:

(x + 3)^2 + (y - 5)^2 = 17

Step-by-step explanation:

To find the radius: distance from point (-2,1) to the center from point (-3,5).

d = sqrt [(-2 - -3)^2 + (1 -5)^2]

d = sqrt [(-2 + 3)^2 + (1 -5)^2]

d = sqrt (1)^2 + (-4)^2 = sqrt 17

Radius = sqrt 17

Equation of the circle:

(x - h)^2 + (y - k)^2 = r^2

h = 3, k = 5, r = sqrt 17

(x - -3)^2 + (y - 5)^2 = (sqrt 17)^2

(x + 3)^2 + (y - 5)^2 = 17

A coin has a diameter of 2.9 cm. If the coin is rolled through 25 complete revolutions, what distance will it travel?
nexus9112 [7]

Answer:

227.75 cm

Step-by-step explanation:

a coin (Circle) with diameter 2.9cm

(radius) r = diameter ÷ 2

r = 2.9cm ÷ 2

r = 1.45cm

1 complete revolutions (perimeter or circumference of a circle ) = 2πr

= 2 × π × r

where r = radius, π is a constant = 22/7

= 2 × 22/7 × 1.45

= 9.11cm

thus in one complete revolution the coin travels a distance of 9.11cm.

therefore in 25 complete revolutions the coin will travel a distance of = 25 × 9.11 cm = 227.75 cm.

The distance covered in complete 25 revolutions of a coin with diameter of 2.9 when it's rolled is = 227.75 cm
