The experimental probability is 9/20 or 45%. Hope this helps!
My day is good how’s yours to
area = pi x r^2
circumference = 2x pi x r or pi x d
1st one diameter = 9.5 cm
so radius = 9.5/2 = 4.75
area = 3.14 x 4.75^2 = 70.85 square cm
circumference = 3.14 x 9.5 = 29.83 cm
2nd one radius = 4
area = 3.14 x 4^2 = 50.25 square cm
circumference = 2 x 3.14 x 4 = 25.12 cm
Answer:
The first choice
Step-by-step explanation:
it is mostly saying you will be testing multiple students or just predicting either way it will be experimental meaning there likely are outliers. however the question is not super clear so this could always be wrong but i hope i helped u
