Answer:

78.5 m²

Step-by-step explanation:

The formula to find the area of a quarter of a circle: \frac{1}{4} * \pi * r^{2}, where r is the radius (diameter ÷ 2) and the \pi is alterable.

1) Substitute the given values into the formula.

= \frac{1}{4} * 3.14 * 10^{2}

2) Solve it.

= \frac{1}{4} * 314

= 78.5

3) Round it off to the nearest tenth. In this case, it has already been rounded off.

Round 30,944 to the nearest ten thousand
Arte-miy333 [17]
Actually none of the answers is correct - it's neither 30,900 nor 40,000.

30,944 rounded to the nearest ten thousand will give us 30,000. It's because 30,944 is closer to 30,000 than to 40,000.

If A = 64 square units, the side length is √64 units (8 units)

If A = 36 square units, that length is √36 units (6 units)
