Step-by-step explanation:
5 is not true becuase E is on the Y axis and 7 is wrong becuase G is on the Orgin.
Answer:
6.3
Step-by-step explanation:
Arc length is circumference
C = 2 * pi *r
We are finding a fraction of the total arc length
A circle is 360 degrees
45 degrees / 360 degrees = 1/8
Find the total arc length and multiply by the fraction of the circle
arc length = 2 * pi * r * 1/8
= 2 * 3.14 * 8 * 1/8
=6.28
Rounding to the nearest tenth

Answer:
The perimeter of the shape is 32.5
Step-by-step explanation:
Since the dashed line is not a perimeter,
we add the circumference of the circle plus the 3 sides of the rectangle
The circumference is of the half circle with its diameter being the opposite side of the rectangle
The opposite side is the length 10
So the radius is half of this which is 10/2 = 5
The circumference of the semicircle is thus;
pi * r = 22/7 * 5 = 15.71
full circle is 2 * pi * r
semi is half of full so we divide formula by 2
So let’s add up
15.71 + 10 + 3.4 + 3.4 = 32.51
Answer:
all you need to do break them step by step.
really good mothed understood?
6+6=12
9+9=18
9+9=18
12+18+18= 48cm
