Answer:
7 packets of grass seed
Step-by-step explanation:
First, find the area of the circular lawn using the formula, A = r²
If the diameter is 20 meters, the radius is 10 meters.
Plug in 10 as the radius and solve for the area:
A = r²
A = (10²)
A = 100
So, the area of the lawn is 100 m² or approximately 314.16 m²
Divide this by 50 to find how many packets of grass seed are needed:
314.16/50
= 6.28
Round this up to 7, since we need to have a whole number answer.
So, 7 packets of grass seed have to be bought.

1. The first one I think you would divide 8 from 64 n get 8 so thats 8%. Answer to that would be the Store.
2. You would!! 56%
3. Multiply 2.5 to 40 and 25. You need a denominator of 100. 62.5/100
So yes you did find at least 60%
I think I did this right. Hope it helps!
