Option C:
Perimeter of the
of a circle = 10.71 cm
Solution:
Given figure is
of a circle.
It is a quarter of a circle.
Radius = 3 cm, Value of <em>π</em> = 3.14
To find the perimeter of the quarter of a circle.
Perimeter of the quarter of a circle formula: 



Perimeter of the quarter of a circle = 10.71 cm
Option C: 10.7 is the correct answer.
Hence perimeter of the
of a circle is 10.71 cm.

area = length × breadth
area = 5.6 × 4.8
area = 26.88
therefore area = 26.88 sq. ft

Answer:
1.20
Step-by-step explanation:
Let mean be represented by M and standard deviation by d. The score will be x and sample number of games be n
To get the test statistic, t for Fernanda's test, we use the formula

Substituting 156 for mean, M then 150 for score x and 30 for standard deviation while 36 for n then

t=1.20 when put in two decimal place
