Answer:
7/10 pi (radians)
Step-by-step explanation:
The formula for sector area is (angle * r^2)/2
140pi = angle*r^2/2
multiply both sides by 2
280pi = angle * r^2
r = 20 cm (substitute)
280pi = angle * (20)^2
280pi = angle * 400
Divide both sides by 400
7/10 pi = angle
To convert a distance of 2790 feet to miles, which ratio could you multiply by?
remember that 1 miles=5280 feet.
so the correct answer is :
1/2 miles .
good luck
8n - 32 + 5m + 33 - 3
8n-32+5m+30
8n-32+30+5m ( rearranging)
8n-2+5m
answer:
5m+8n-2 or 8n+5m-2
Since they are already in order you know the 22 and the 61 are the upper and lower extremes. To find the median you find the number that is in the middle which is 42. To find the lower quartile find the middle number starting from the first number and the number to the left of the median (22 and 36 in this case). The loser quartile is 25. To find the upper quartile, fine the middle number between the number to the right of the median and the last number (44 and 61 in this case.) the upper quartile is 57 you then just plot it and graph it
