7 times 2 = 14
Answer:
The length of the arc is 7.85 in
Step-by-step explanation:
First of all we need to calculate the circumference
To solve this problem we need to use the circumferenc formula of a circle:
c = circumference
r = radius = 10 in
π = 3.14
c = 2π * r
we replace with the known values
c = 2 * 3.14 * 10 in
c = 62.8 in
The length of the circumference is 62.8 in
Now we have to get the relation of the sector with the circle, for this we divide 45° by 360°
45° / 360° = 1/8
we multiply this fraction with the circumference and obtain the length of the arc
62.8 in * 1/8 = 7.85 in
The length of the arc is 7.85 in
4485 square feet of grass ... 3/4 of an hour
x square feet of grass = ? ... 1 hour
If you would like to know how many square feet of grass can be fertilized per hour, you can calculate this using the following steps:
4485 * 1 = 3/4 * x
4485 = 3/4 * x /*4/3
x = 4485 * 4 / 3
x = 5980 square feet
Result: 5980 square feet of grass can be fertilized in one hour.
