Answer:
central angle ( θ) = 1.91875radians
central angle ( θ) in degrees = 109.92degree
Step-by-step explanation:
Given:
diameter of 320 millimeters
Then the Radius of the circular
brake drum can be calculated as
Radius =Diameter/2
Radius = 320 millimeters/ 2
Radius= 160 millimeters
central angle ( θ) = arc/r
central angle ( θ) = 307 millimeters /160 millimeters
central angle ( θ) = 1.91875radians
Than to convert it to degrees we have
1rad × 180/π = degree
Where π =3.142
central angle ( θ) = 1.91875radians * 180/π
Therefore,central angle ( θ) in degrees = 109.92degree
Answer:
Part a)
Part b)
Step-by-step explanation:
we know that
The scale is
That means
2.4 cm in the model represent 1 foot in the real
Part a) we know that
The restaurant is 20 feet tall
Find the height of the model
Multiply the actual height of the restaurant by the scale 2.4
A bottle cap is 1.2 cm tall
To find out the number of bottle caps divide the height of the model by 1.2
Part b) we know that
A popsicle stick is 15.2 cm tall
To find out the number of popsicle sticks divide the height of the model by 15.2
Convert to mixed number
