Answer:
Step-by-step explanation:
The original questions is suppose an ant walks counterclockwise on a unit circle from the point (1,0) to the endpoint of the radius that forms an angle of 240 degrees with the positive horizontal axis.
To find the distance ant walked we find the arc length of the sector with central angle 240 degree and radius =1 (unit circle)
arc length of a sector =
arc length of a sector =
arc length of a sector =
Answer:
16, 100, 1,
Step-by-step explanation:
A perfect square is a number multiplied by itself to get that number. So 16 would be 4*4 and 100 would be 10*10, then 1 would just be 1*1
It is true. Guptas did figure out the earth was round by observing lunar eclipses.

I will not give in answer but will give an example
Step-by-step explanation:
The area of irregular shapes can be determined by dividing the given shape into smaller regular shapes. The area of irregular shapes can be determined by dividing the given shape into smaller regular shapes.
In real life figures are often irregular shapes - a little bit messy. Think of your messy bedroom once more ‐ is it a perfect rectangle?
The trick is to break these figures into shapes that you know well and whose area you know how to find.
1. Find the area of this room:
3- 2 -4 -6 irregular shape
This can be done in two different ways but ill only give one example on how to find an area.
Method #1
Divide the figure into two rectangles and find all missing lengths.
The larger rectangle has an area of
4cm x 7cm = 28cm2
The smaller rectangle has an area of
4cm x 2cm = 8cm2
If we combine these we will find the total area:
28cm2 x 8cm2 = 36cm2
hope this helps :)
