Sector area = 0.5 * r^2 * angle (in radians)
so:
16 pi = 0.5 * r^2 * (90*pi/180)
r^2 = 16 pi /(0.25 pi) = 64
r = 8
therefore it would be d
Answer:
7.5 nuts each day
Step-by-step explanation:
(2*7)+(3*7)=35 spoons of nuts
35*3=105 nuts in two weeks
105/14=7.5 nuts each day
m3 = 110°
Step-by-step explanation:
m1 = 180° - m4 ( sum of angles in a straight angle )
m1 = 180° - 150° = 30°
m3 = 180° - (m2 + m1) ← sum of angles in a triangle
m3 = 180° - (40 + 30 )° = 180° - 70° = 110°
Answer: -2(1/2)
Step-by-step explanation:
I CAN HELP A GIRL OUT!
anyways...
calculate the difference first.
(-13/12) - 14/9
then, rewrite the expression.
-13/12 - 14/9
the solution is -95/36.
when it's converted to decimal form, it turns into -2.638. so, our BEST estimate for the value of the expression is -2(1/2) (the second option)
