Also written as 22/7 as a fraction
The radius of the circle is 2.86 cm.
Step-by-step explanation:
Given,
The circumference of the circle = 18 cm
To find the radius of the circle.
Formula
The circumference of a circle of radius r is 2πr
According to the problem,
2πr = 18
or, r = = 2.86 (approx)
Hence,
The radius of the circle is 2.86 cm.
The correct answer is D 14/3
To factor the trinomial, you can use the ac method where you multiply the first and last terms together (6 and 9) and add up to 15.
In this case ac= 54
2 numbers that multiply to 54 and add up to 15 would be 6 and 9 so place these numbers where the 15 would be:
Then group terms to simplify:
Simplify any like terms:
And group together again:
You can simplify a 3 out of the first expression one more time to get:
Which would be the factored form. I hope this helps :)
first change the 5.63 to standard form as
so now multiplying with the 10^6
applying the first law of indices
