Step-by-step explanation:
circumference = 2πr
5) 2πr
=2π(7)
= 43.98 mm
7) 2πr
=2π(29) -> 58÷2=29
=182.21 yd
72⁰_______3π m
360⁰______15π m
C = 15π = 2π r
r = 7•5 m

Step-by-step explanation:
Factor by grouping.
First you need to know some rules 2 numbers that are the same with coefficients divided : you differentiate those coeff
and multyplied :you sum up them
12x^8/3x^3= 4x^8-3=4x^5
20^2x=20^x*20^x
m^5*m^-7=m^5-7=m^-2
Answer:
39°
Step-by-step explanation:
IM assuming xyz is a triangle
180 - 113 - 28 = 67 - 28 = 39
