644 divided by (8 x 8) (8x8) equals 61 so 644 divided 61 equals <span>10.557377049</span>
I believe its because anything above 5 is rounded up, 7 rounded up is 8 and how I was taught is if its a number (this case its 751,447) the 7 in it would round to 8 causing all the other numbers to go up as well causing the 800,000 >.< I

d/2=r
big diameter=20.4, so radius i 20.4/2=10.2cm
small is 10.8/2=5.4
so
big-small
pi10.2^2-pi5.4^2
pi(104.04-29.16)
pi(74.88)
using 3.14=pi

answer is B
Answer:
x + (x-42.2) = 90
2x - 42.2 = 90
add 42.2 to both sides
2x = 132.2
divide each side by 2
x = 66.1
find the measure of the other angle
66.1 - 42.2 = 23.9
