Georgina walk 23 floor
30 - 7 = 23
To find the formula to find radius, solve for r using the formula for circumference.
to solve:
1. divide each side by 2

2. you get
r = c/2
Answer:

Step-by-step explanation:
So we know that:

To reflect across the <em>y-axis</em>, instead of x, use -x. Therefore:

Simplify:

And that's our answer :)
Answer:
38.13 ft squared
Step-by-step explanation:
Since it is half of a circle we first find the area of a normal circle then divide by two.
So to find the area of a circle it is pi times radius squared which in this case it would be 3.14 times 9 = 28.26
Then since it is a half circle we divide by two so
28.26/2 = 14.13
Then to find the area of the triangle we do 4 times 6 which is 24.
now we add the two which is 14.13 + 24 which is
38.13
