Answer:
Step-by-step explanation:
The formula for the area of a sector is
where theta is the measure of the central angle (which is the same measure as that of the arc that is intercepted by the 2 radii formig the angle), and r is the radius.
For us, theta is 90 degrees and r is 20. Filling in the formula:
which simplifies down a bit to
so
A = 314 m squared
Answer:
24 minutes
Step-by-step explanation:
This can be explained with the equation y=2x+10 (I chose 2 arbritrary variables, any are acceptable). A week is equivalent to 7 days so x=10. Plug this into the equation and you end up with 24, because 2(7)+10=24
Answer:
Step-by-step explanation:
First verify that they are similar by comparing the ratio of known sides
7/5 = 1.4
(7/2)/ (5/2) = 1.4
As these two are identical, we have similar triangles and the third sides will have the same ratio
6/h = 7/5
h = 6(5/7) = 30/7 = 4 2/7
