Find the area of circles whose diameters
(a)14 cm
(b) 28 cm
​

(a) 153.93804

(b) 615.75216

Step-by-step explanation:

(a) A=πr2

14 divided by 2 =7

=π*7 squared =153.93804

(b) A=πr2

28 divided by 2= 14

=π*14 squared=615.75216

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.

answer: y=0 if that is what u r looking for
