Distribute the negative to the 16 and into the -5
-16+5x
The formula for this is
A = P(1 + r/100)^n where P = initial investment, r = compound interest as per cent, and n = number of years.
so here we have
A = 12000(1 + 1.5/100) ^ 2 = 12000 * 1.015^2 = £12,362.70
We know that
AE*EC=DE*EB-----------> <span>String theorem
AC=8 in----------> AE=AC/2----------> AE=4 in
EC=AE-----------> EC=4 in
BE=2.5 in
DE=?
DE=(AE*EC)/EB----------> DE=</span>(4*4)/2.5---------> DE=6.4 in
<span>
then
diameter=DE+EB--------> 6.4+2.5=8.9 in
the answer is
the diameter is 8.9 in

Try this:
1) for square a=5*2=10.
for circle r=5.
2) for square S'=10²=100; for circle S°=πr²≈78.54.
3) for half of circle S₁=0.5*78.54=39.27
4) for shaded region S=S'-S₁=100-39.27≈60.73
Answer: G (60.73)
