c
Step-by-step explanation:
10*10=100

so rounded answer is c or 21.5
goodluck on your test
The radius is ( by the way I am not sure ) 181.458......
It is none of them
9x³ - 4x³ = 5x³
3x² - -2x² = 3x²+2x² = 5x²
-3 - 16 = 13
So :
5x³ + 5x² +13
The sum of interior angles of a convex quadrilateral is 360°, so the average angle is 90°. If two of the angles are actually 90°, the remaining two are 90° ± (10°)/2, so are 85° and 95°.
The angles are 90°, 90°, 95°, 85°.
