Answer:
17/100
Step-by-step explanation:
If the hoop rotates (3/2)*pi radians in 1 second, then we multiply by 60 seconds to get the angular distance it rotates in 1 minute:
(3/2)*pi*60 = 90*pi radians in 1 minute.
Then since 1 revolution has 2*pi radians, we divide 90*pi/2*pi = 45 (with no remainder). Therefore, the hoop makes 45 revolutions per minute.
Answer: 14.8units²
Step-by-step explanation:
The formula for calculate the area of a triangle is:
Where b () is the base and h () is the height.
The formula for calculate the area of a semicircle is:
Where r is the radius.
As you can see, the diameter is 5 units, then the radius is:
The area of the figure is the sum of the area of the triangle and the area of the semicircle.
Then, the result is:
