4.05 x 10^-2 Standard Form

Mathematics
1 answer:
defon3 years ago
5 0

Answer:

0.0405

Step-by-step explanation:

10^-2 is the same as 1/100, so if you multiply 4.05 x 1/100, you get 0.0405.

Another way to think about it is by looking at the exponent -2.  You need to move the decimal point 2 spaces to the left -- and add zeroes to any spaces that don't already have numbers.

So if you start with 4.05, and move the decimal one space to the left, you get 0.405, and then you move it one more space, and you get 0.0405.

18.84

Since the formula of circumference is C = 2 pi r or C = pi times diameter, you can conclude that the circumference is 18.84.

Assuming that pi is 3.14 in this case rather than the full pi or just in terms of pi.

Hope this helps!
