Question

I just really need a help guys thank u mwa

Answer 1

A. 1256
`ft^(2)` B. 26 pounds C. $172.90

Explanation:

PART A

1st find the radius of the area

radius = diameter / 2

r = 40/2

radius = 20ft

Area of circle = radius^2* pi

Area = 400 * 3.14

Area = 1256
`ft.^(2)`

PART B

1256 / 50 = 25.12

Because we can only buy full pounds and we need the whole area to be reseeded, we round 25.12 to 26.

26 pounds of seeds will be needed to reseed the whole area.

PART C

Multiply the number of pounds of seeds needed to be bought by 6.65

26 x 6.65

$172.90 for the total cost of grass seeds

Answer 2

See below

Explanation:

My man, how did you even get these numbers??? no whole number multiplied by 6.65 even equals 22??? Regardless, here's what I did.

a) r = 40/2 = 20

A = πr^2 = (3.14)(20)^2 = 1256

b) 1256/50 = 25.12 basically, 26

c) 26 x 6.65 = 172.9

Thoughts and prayers my guy. Keep trying
