You'd need to find the distance AROUND the garden, which is also PERIMETER.
To find the perimeter of a circle, you use the following equation:

=


=
25.13 ft I don't know what your answer options are, but chose the option closest to 25.13 ft
Answer:

a. We get 56 heads out of 100 tosses.
We will use one sample proportion test
x = 56
n = 100



Formula of test statistic =
=
=
refer the z table for p value
p value = 0.8849
a. We get 560 heads out of 1000 tosses.
We will use one sample proportion test
x = 560
n = 1000



Formula of test statistic =
=
=
refer the z table for p value
p value = .000148
p value of part B is less than Part A because part B have 10 times the number the tosses.
