He would earn $10 in 4 hours
You would have to divide $22.5 by how many hours he worked so it would be 9 hours. Once u divide, that’s how much he earns hourly. So your next step is to multiply what he earns hourly ($2.5) by 4 hours because they’re only asking how much he earned for 4 hours.
Since the volume of an object = \frac{4}{3}\times \Pi r^{3}
Volume= \frac{4}{3}\times (3.14) (243)^{3}
Volume= 60074091 mm^{3}
<span>So we need to find the value of 8.3*24.2*0.03 and round it to the nearest hundredth. So lets multiply the numbers first: 8.03 * 24.2 * 0.03 = 6.0258 and now we need to round it to the nearest hundreth. The nearest hundreth is .03 and we get: 6.03 so the correct answer is D.</span>
