Answer:
64 mm² or approximately 201.06 mm²
Step-by-step explanation:
If the diameter is 16 mm, the radius will be 8 mm.
Use the circle area formula, A = r², where r is the radius. Plug in 8 as r:
A = r²
A = (8²)
A = 64
So, the area of the circle is 64 mm² or approximately 201.06 mm²
Answer:
The horizontal distance between the parking lot and the launch site is 470 meters
Step-by-step explanation:
Let
x-----> the horizontal distance between the parking lot and the launch site
we know that
The tangent of angle of 12 degrees is equal to divide the altitude of 100 meters by the horizontal distance
so
tan(12°)=100/x
Solve for x
x=100/tan(12°)=470 meters
Her avarage speed in miles per hour is 54
How i solved this was by 135/2.5 and i got 54
I hope this helps!
