yes, it is. Got both answers correct. 396,453,888 and 4589. I needed to multiply by the partial day 24/7.3. Then, it worked. That was the missing piece. Thanks again!

Physics
(2)(3.14)(3.00)(6.4 x 10^6)(3.288) = 396,453,888 m 24/7.3 = 3.288 396,453,888 / 86,400 = 4,589

Thanks, Steve. Still get the wrong answer. I don't know what I'm doing wrong. One of the practice problems is 5.80 radii and 19.6 hours. It gives the answers as 284,000,000 and 3287. I get how they got the velocity, but not the distance. Since I haven't been able ...
