Answer:
its 45 as3*15 is 45 and 45*1 is 45
plz mark me branliest
Radius is 16in
Circumference is 2xpiXradius
So 100.5 inch
B
Step-by-step explanation:
Answer:
The rate of change of a function with respect to a variable.
Step-by-step explanation:
For example: The slope of a constant value (like 3) is always 0. The slope of a line like 2x is 2, or 3x is 3 etc. and so on.
Answer:
50.2655 m2 of grass turf to the interior center area.
62.8319 m2 of asphalt to the running lane.
Step-by-step explanation:
If the diameter of the interior center is 8 meters, its radius is 8/2 = 4 meters.
So, the area of the interior center is:
Area = pi * r^2 = pi * 4^2 = 50.2655 m2
It will be needed 50.2655 m2 of grass turf to the interior center area.
To find the area of the running lane (for the asphalt), we just need to subtract the area of a circle with 6 meters of radius (4 m from the interior circle plus 2 m from the width of the lane) from the area of the interior circle (radius = 4):
Area of lane = pi * 6^2 - pi * 4^2 = 62.8319 m2
It will be needed 62.8319 m2 of asphalt to the running lane.
