3. recognize effects how did the beliefs and practices
of islam create unity and strength among muslims in
the 600s?

Hello!

Explanation:

The Arabs were never really unified before Islam. But Islam taught them and unified them under one religion where they were all Muslims and that was what mattered to them. But after the death of prophet Muhammad they could not definitively answer the question on who should they follow and that split the religion into Shi’a and Sunni Islam that is still prevalent today.

the right answer is the constitution

254.34

step-by-step explanation:

the formula for area of a circle is given by

a = pi * r^2

a = pi * 9^2

a = 81*pi

using 3.14 as an approximation for pi

a = 3.14*81

a = 254.34
