Let's cancel out from left to right

$\\ \sf\Rrightarrow 0.02349$

$\\ \sf\Rrightarrow 0.0235\times 10^{-1}$

$\\ \sf\Rrightarrow 2.35\times 10^{-3}$

Option C is correct

Answer: The answer is (B)

Explanation: The answer is (B) because, there are 2 zeros so that means that there would have to be a 2 behind the 10 and then there is 2,3,4,and 9. We take out the 9 and use the other numbers, bring over the decimal and now you have $2.34 x 10^{2}$ .

Find the area of a circle that has a diameter of 60 feet.

IrinaK [193]

Answer:

60π

Step-by-step explanation:

Hullo :D

I think this will be a piece of helpful info:

<em>The formula for finding the area of a circle if πd.</em>

<em />

In that case, we just substitute 60 (our d)

So the area will be 60π

If you want that multiplied, you'll get 188.4 (multiplying by 3.14)

Thus, the answer is $$\boxed{60\pi}$ .
