Answer:
x = 28
m∠ACD = 68°
Step-by-step explanation:
∠BAE ≅∠DAC because they are vertical angles
∠ACD = 180 - 124 = 56°
to find 'x': 56 + 2x + (180 - 4x) = 180
236 - 2x = 180
-2x = -56
x = 28
m∠ACD = 180 - 4(28) = 180 - 112 = 68°
Answer:
112
Step-by-step explanation:
32*2+29*2=112
Answer:
a
Step-by-step explanation:
368
Assuming that the balls are perfect sphere, then we can use the formula for the volume of the sphere to solve the volume of the ball. the volume of a spher is given by the formula:
V = (4/3) pi r^3
where pi = 3.1416
r is the radius
since D = 9 in
r = 4.5 in
V = ( 4/3 ) (3.1416) ( 4.5)^3
V = 381.7 cubic inches is the volume of one of the balls.
