Answer:
ok so 10 times 4 equals 40 and then 40 times six equals 240 but I don't know what standard notation is
One way of doing this would be to look at the πr² as if it were a single term. Then we could divide both sides by πr², which leaves h = V/πr².
Answer:
a = 70 km/h - 20 km/h / 0.008 h = 50 km/h / 0.008 h = 6250 km/h²
