The diameter of a circular tablecloth is 72 inches. find the area and circumference. use 3.14 as an approximation for pi.

show work

Part 1) The area is

Part 2) The circumference is

Step-by-step explanation:

step 1

Find the area

we know that

The area of a circle (circular tablecloth) is equal to

we have

------> the radius is half the diameter

substitute

step 2

Find the circumference

we know that

The circumference of a circle (circular tablecloth) is equal to

we have

substitute

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)

im pretty sure its
