Round 8.85 to the nearest hundredths.
geniusboy [140]

Answer: 8.85 rounded to the nearest hundredths place is 8.85

Step-by-step explanation:

The hundredths place is at 0.0x <--(where the x is).

So rounding from the thousandths to the hundredths is 8.850 = 8.85

Simply put, 8.85 is rounded to the nearest hundredths itself already.

Rounding to the nearest <em>10th </em>place however, would give you 8.9.

Hope this helps!

Step-by-step explanation:

Let

c = 11.5 cm

a = 8.9 cm

b = ?

Since this is a right triangle, we can use Pythagorean theorem to find the length of side b:

c^2 = a^2 + b^2

\Rightarrow b^2 = c^2 - a^2

Taking the square root of the equation above, we get

b = \sqrt{c^2 - a^2} = \sqrt{(11.5\:\text{cm})^2 - (8.9\:\text{cm})^2}

\:\:\:\:=7.3\:\text{cm}
