Trisha measured the button on her coat. Then she calculated that it has an area of 50.24 square millimeters. What is the button's circumference? Use 3.14 for . *

25.12 milimeters

Step-by-step explanation:

Hi, to answer this question, first, we have to calculate the button's radius:

Area of a circle= π radius^2

Replacing with the values given:

50.24 = 3.14 r^2

50.24 / 3.14 = r^2

16 = r^2

√16 =r

r= 4 mm

Now, to find the circumference

Circumference = 2πr

Replacing:

C = 2 (3.14) 4 = 25.12 milimeters

Feel free to ask for more if needed or if you did not understand something.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
