No it would be Pi *r *r because the r is to the power of 2
32.5 square feet. If you do the area formula “A=5v13(13) over 2”
I would say that the "n"th term of the sequence is 41, as the pattern increases by 10 every term.
First, convert 5 and 24/10 into a mixed fraction:
5 and 24/10 = 74/10
Now, divide 74/10 by 4:
74/10 ÷ 4 = 74/10 × 1/4
= 74/40
= 37/20
= 1 and 17/20
(Remember that dividing requires you to reciprocate 4)
Hope this helps!
