Where do i put parentheses to make a statement true

i got 10.28 but that rounds up to 10.3

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
