This is easy bro,
So first, all you have to do is finding the half circumstance,
the formula for circumstance is:
C=π*d
since the diameter is 8, therefore,
C=π*8
C=8π,
using 3.14 for π,
8*3.14=
25.12
Hope this helps!!!!
$5.25, because if you multiply $6 by 7/8(fraction form), you get $5.25
Un grouping in 3rd grade maths can also be called subtracting
Amber could have used cross multiplication.
Have a great day!!!!
I think you add the numbers together, and then divide by three
