Well after reading this 100 times I haven't found a 100% sure answer but I think its A
hope its right and it helps :D
Answer:
The angular speed of the wheel in radians per second is 0.66.
Step-by-step explanation:
Recall the following statement:
A linear speed (v) is given by,
...... (1)
Here,
represents the angular speed of the wheel and <em>r</em> represents the radius of the wheel.
From the given information:
Linear speed (v) = 33 cm/s
Radius of the wheel (r) = 50 cm
Now to find the angular speed in radian per second.

Divide both sides by 50.

Hence, the angular speed of the wheel in radians per second is 0.66.
Answer:
3,781
Step-by-step explanation:
To solve this problem, we will find the area of the whole circle and use that to find teh area of the 60º section.
First, recognize the formula for the area of a circle:
A = 3.14
In this scenario, the radius (<em>r</em>) is 85 feet:
A = 3.14(85
A circle is 360º and we only require the area of 60º. 360º / 60º = 6 so we will divide by 6:
A = 
Finally, we will simplify and round:
A = 3,781
