Answer:
Well on my end i got 47.12, with pi included
Step-by-step explanation:
1. Area of a circle is pi(R)^2 , where R is the radius. So we can substitute:
22/7(16^2) = about 805 meters squared.
2. Let's find the area of the rectangle first.
A=LW
A= 18(10)
A= 180 cm squared.
Now the semi-Circle:
The radius of the circle is 9 (because 18/2 is 9). Now we plug in to the area formula:
22/7(9^2) = about 254 cm squared. But because that is the area of the whole circle, and we only need half of the circle, we divide that value by 2 to get:
127 cm squared for the semi-circle.
Now we add up the rectangle and semi-circle's areas:
180 + 127 = 307 cm squared as your answer.
I hope this Helps!
B. The square root of 180 and 3 the square root of 20 are equal
Answer:
14080 ft
Step-by-step explanation:
You want to convert 4 mph to ft/min and then mult. the result by 40 minutes:
4 mph 5280 ft 1 hr
---------- * --------------- * ------------- = 352 ft/min
1 1 mile 60 min
Now multiply this rate (speed) by 40 minutes:
352 ft 40 min
---------- * ------------ = 14080 ft (answer)
min 1
This would be the same as 2 2/3 miles (in 40 min)
