—radius is 1/2 the diameter so if the diameter is 6, the radius would be 3.
—the circumference is 2pier
so you would use your calculator and use the pie symbol or 3.14 and multiply 2*3.14*3 (3=radius for my example)
— the area is pie r^2
so you would multiply 3.14*3 squared
Answer:
720
Step-by-step explanation:
Since we are choosing a subset of 3 people from a set of 10 people, and arranging the 3 people according to relative strength, the answer can be obtained by computing P(10,3).
P(10,3)=10! / (10-3)!
= 10!/7!
Rewrite 10
! as
10 * 9 * 8 * 7
! / 7!
Cancel the common factor of 7
! and divide (
10 * 9 * 8
) by 1
10 * 9 * 8 = 720
Answer is 73 because blah blah blah blah
Answer:
