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 meter = 1/1000 km
1 second = 1/3600 Hour
1m/s = (1/1000)/(1/3600)
1m/s = (1/1000) x (3600/1) = 18/5 = 3.6
so 1 m/s is equivalent to 3.6 km/h
And 60 m/s = 60 x 3.6 = 216 km/h
