Answer:
7.9577cm^2
Step-by-step explanation:
10 = 2 * r * pi
==> r = 5/pi
area = r * r * pi = 25/pi = 7.9577cm^2
Answer:
the angle of reflection is the angle between the reflected wave and the "normal" (the perpendicular line to the reflecting surface).
Step-by-step explanation:
I believe it’s 82
8x=3x+8+4x+10
x=18
4•18+10=72+10=82
Answer:
-4h < - 14
We solve for h by applying the inverse operations;
The inverse operation of multiplication is division, so we divide by -4 on both sides;
/-4 /-4
h < 3.5, it could be <u>3.4, 3.3, 3.2 3.123, 2.4, 2.576</u>, there are tons of numbers below 3.5.
<u>So anything below 3.5 would best be suitable for the equation.</u>
Try to calculate them in your head and if that doesn't help use a calculator. I hope this helps
