Answer:
4 m
Step-by-step explanation:
The circumference of a circle is the product of π and the diameter.
C = πd
12.56 m = 3.14d
d = 12.56 m/3.14 = 4 m
The rug's diameter is 4 meters.
is it factorisatiom or solving equation?
Step-by-step explanation:
2m² + 2m - 12 divide the equation by 2
then: m² + m - 6
factorise: (m + 3)(m - 2)
solve m + 3 =0 or m - 2 =0
m= -3 or m = 2
