Answer: 8pi

--------------------------------------

Explanation:

A = 16pi is the area, which means
A = pi*r^2
16pi = pi*r^2
16 = r^2
r^2 = 16
r = sqrt(16)
r = 4 
is the radius

Use this to find the circumference C
C = 2*pi*r
C = 2*pi*4
C = 8pi
The exact circumference is 8pi inches long

The local ice cream parlor sells an average of 11 milkshakes a day for $3.99
Greeley [361]

In a week, the parlor would make about $300 from milkshakes

Total amount = number of milkshakes sold in a week x price of a milkshake

There are 7 days in a week, in a week the parlor would sell : 11 x 7 = 77 milkshakes

price of a milkshake = $3.99

Find an equation of the circle that has center (-4, 1) and passes through (3, -5)
Lemur [1.5K]

The general equation for a circle with center (a,b) and squared radius k is


(x-a)^2 + (y-b)^2 = k


Here we have


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


and the constant is fixed by substituting in the point we know (x,y)=(3,-5)


(x + 4)^2 + (y-1)^2 = (3+4)^2 + (-5-1)^2 = 85


Answer:


(x + 4)^2 + (y-1)^2 = 85
