Answer:
At least 26 questions to get around an 82% not 25 because that equals 78%
Step-by-step explanation:
Take h common:
h(B + r) = 25
Divide b+r
h = 25/ b + r
Subtract bh:
hr = -bh + 25
Divide h:
r = -bh/h + 25/h
Simplify:
r = -b + 25/h

Answer:
.
Step-by-step explanation:
So the standard form of a circle is
where (h,k) is the center and r is the radius.
You are given (h,k)=(1,4) and r=2.
So we are going to plug in 1 for h, 4 for k, and 2 for r:

195195/3 = 65065
so 65064+65065+65066 = 195195
