The formula for the area of a circle is
We know the diameter, and the radius is half of the diameter. So the radius is 9. Now we plug that into the formula.
So the answer is B, 81 pi square feet
MCE = 360 - (150 + 70 + 50)
mCE = 360 - 270
mCE = 90
<CDE = 1/2(mBE + mCE)
<CDE = 1/2(150 + 90)
<CDE = 1/2(240)
<CDE = 120
answer
<CDE = 120°
Answer:
-13t - 5z
Step-by-step explanation:
-6t + 2z - 7z - 7t
= -13t - 5z
70 / 14.7 = 4.8
the correct answer is 4.8
