To do the scientific notation you would:
Multiply the coefficients and then round the number of significant figures into the coefficient with the smaller number.
Then you would add your exponents
And then your result is converted into the scientific notation.
Hope this helps! :3
Speed =distance/ time taken =100/0.4 =250 miles/ hour
Answer:
The correct answer is 3πcm
Step-by-step explanation:
The length of an arc is calculated using the formula P=∅/360×2πr
where ∅is the angle the arc subtends at the center of the circle, and r is the radius of the circle of which the arc is part.
2r gives the diameter which from the diagram corresponds to AB=36 cm
therefore P=30/360×π×36
=3πcm
It's a scalene triangle, a triangle where all of the sides are different lengths.
