The area of a circular garden is 121pi
2 answers:
Answer:
1. Use area to find radius.
A = π r^2
121 π = π r^2
2. Divide each side by π.
121 = r^2
3. Take in the square root
.

11 = r
4. Find the circumference
.
C = 2 × π × r
C = 2 × π × 11
C = 22 π ft
Answer:
22 pi ft
Step-by-step explanation:
We can use the area to find the radius
A = pi r^2
121 pi = pi r^2
Divide each side by pi
121 = r^2
Take the square root
sqrt(121) = sqrt(r^2)
11= r
Now we need to find the circumference
C = 2*pi*r
C = 2* pi *11
C = 22 pi ft

Answer:
D. 11.25 students per year
Step-by-step explanation:
Because it will be half2 standard deviation which will include 500-700.
2std will include from 300-700.
so it will be half of 95%.
Two negatives is a positive so the equation is Z+3/4=13/2
-3/4
Z=26/4-3/4
Z=23/4
