Scientific notation is just rewritten so that it has a single digit in front of the decimal and that this is multiplied by a power of ten that makes this decimal equal to the original number.
In this case we have 2.67 million. Well a million is equal to 10^6, because 10*10*10*10*10*10=one million.
So in scientific notation you would write:
2.67X10^6
Step-by-step explanation:
Solution,
Area=38.5 cm²
by using the formula of are of a circle i.e, πr², we get
πr²= 38.5 cm², where π=22/7
r²=38.5 cm²/π
r²=12.25 cm²
r=√12.25 cm²
r=3.5 cm
Now, by using the formula of circumference of a circle i.e, 2πr, we get
2πr=2×π×3.5 cm, where π=22/7
=22 cm
So, the circumference of the circle is 22 cm.

Answer:
Reflection
Step-by-step explanation:
SAS congruency criteria:
- 2 sides of both triangles are equal
- the angle between these two sides of both triangles are equal
Then, if the two triangles share a common side and satisfy the SAS criteria, reflection would map one onto the other.
