Diameter=side
find area of field (square) and area of sprinkler (circle)
ara of square=side^2
area of circle=pir^2
area of square=12^2=144
area of circle=pir^2
d/2=r
12/2=6=r
area=pi6^2
area=36pi
aprox pi=3.14
area=113.04
area wasted=area of field-arrea of sprinlker
area wasted=144-113.04=30.96 m^2
Answer: $5289.35
Step-by-step explanation:
Since the cars have an average mileage of 6.78 miles per gallon and the race is 500 miles, the number of gallons each car will take will be:
= 500/6.78
= 73.75 gallons
Since they're 44 cars, the total gallons of fuel will be:
= 44 × 73.75
= 3245 gallons
Since the fuel cost is $1.63 per gallon, the total fuel cost, will be:
= $1.63 × 3245
= $5289.35
I think it’s F I’m not sure if it’s correct !
Answer:
25 miles
Step-by-step explanation:
Given: A boat sail 20 miles west of the port and then 15 miles south to an island.
Picture attached.
The distance from port to island could be measured in a straight line. It will form a hypotenous.
∴ we can use Pythogorean theorem to find the distance.
Where, "a" is adjacent= 20 miles and "b" is opposite= 15 miles.
⇒ 
⇒
⇒
We know 
.
∴
∴ Distance of Port from the Island is 25 miles.
