C=2πr
C=πd
A=πr^2
r=C/2π
r=1/2 d
<u>By the way all you do to solve r is: </u>
C=2πr
C/2π=2πr/2π
C/2π=r
r=C/2π
Hope this helps:)
A looks like the correct answer
Answer:
that depends
Step-by-step explanation:
how many students are in the school all together, see you would do the 3 boys over the number of people (or students) in the school
hoped this helped a little
Answer:
AT = 8
Step-by-step explanation:
Using the sine ratio in the right triangle
and sin45° = 
sin45° =
=
= 
Multiply both sides by AT
AT × sin45° = 8, that is
AT ×
= 8
Multiply both sides by 
AT = 8
