A circle has circumference 6 inches. What is
the area of the circle?

it is 2.86

Step-by-step explanation:

your welcome

A= about 2.87 inches

Step-by-step explanation:

2pir=6

pir=3

r= 0.96

pir^2=A

pi(0.96)^2=A

pi(0.9126)=A

A= about 2.87 inches

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
