Circle graphs
A circle graphs is a graph that represent data using section of a circle.

Sector-section of a circle forward by 2 radii and the are of a circle connecting the 2 radii. pets of students

1. What is the title > in Mr.w's class
2. What are the different cat gerios represented by the graph (24 students) cats,dog,other,don't have pet,
3. What percent of the class has a dog?How away students have a dog 25precent





4.% of class with cats?how many students have a cats? 33% 8 kids
1/3 of 34
5. What % of the circle is represented by all the sector 100%
6.Would this graph make sense if the titleof sector able were missing

Find the diameter of a circle with a radius of 12.6m.
Show the formula you used and all the work.
d=2r
d=2(12.6)
d=25.2m.♫♫♫

Find the radius of a circle when the diameter is 10.5cm.
Show formula and work.
r=d/2
r=10.5/5
r=5.25cm.

Find the circumference of a circle with a diameter of 3mm.
Show formula and work.
c=pi d
c=(3.14)(3mm)
c=9.42 mm.♦

Find the circumference of a circle with a radius of s.m.
Show formula and work
c=2pi r
c=2(3.14)(5)
c=10 314
c=c=31.4m.

Find the diameter of a circle with a circumference of 12.56 cm.
Show formula and work
d=c/35
d=1256/3.14cm
d=4cm.☻

Find radius of follow circles
d=4cm
d=10cm
c=15.7m
c=3.14cm.
