Answer:
3.6
Step-by-step explanation:
tan61=x/2
2(tan61)=x
3.6=x
The area of a circle can be found using:
pi x r^2 (where r is the radius)
If the area of the circle is 255pi, then:
pi x r^2 = 255pi
Now we need to make r the subject:
r^2 = 255 (cancel the pi on both sides)
r = square root of 255
r = 15.96871942
Answer: 15.96871942 feet
Hope the answer helps :)
This is the number of combinations of 4 from 12
12C4 = 12!
----------
4! 8!
= 12*11*10*9 11*5*9 = 495
-------------- =
4*3*2*1
They lost L games.
They won W games.
W = 2L
W + L = 96, but W = 2L, so
2L + L = 96
3L = 96
L = 32
W = 2L = 2 * 32 = 64
They won 64 games.
