Abaker uses a coffee mug with a diameter of 8 cm, to cut out circular cookies from a big sheet of cookie dough. what is the area a of each cookie? give your answer in terms of pi. a=

A =

Step-by-step explanation:

∵ The diameter of the mug is 8 cm and using to cut out circular cookies

∴ The diameter of each circular cookie is 8 cm

∴ Its radius = 8 ÷ 2 = 4

∵ Area of the circle =

∴ Area =

answer: ok

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)
