i have no clue
2147.76 in³
This question is basically just asking you to take the volume of the entire ball and subtract the volume of the core (the part that's not polyurethane) to find the volume of the polyurethane. The formula for the volume of a sphere is \frac{4}{3} \pi r^{3} where r = the radius. First, let's find the volume of the whole sphere. V=\frac{4}{3} \pi 9^{3} V=\frac{4}{3} \pi 729 V=\pi 972 Now let's find the volume of the inner core. V=\frac{4}{3} \pi 6^{3} V=\frac{4}{3} \pi 216 V=\pi 288 972π - 288π = 684π Use 3.14 for π and we get 684*3.14 = 2147.76 in³.
Will you help me with one more please??
sure
Find the volume. V = pi * r^2 * h V = 3.14 * 15^2 * 40 V = 3.14 * 225 * 40 V = 28260 Find 80%: 0.8 * 28260 = 22608 Find the volume of the spherical foam pellets: V = 4/3 * pi * r^3 V = 4/3 * 3.14 * 3^3 V = 4/3 * 3.14 * 27 V = 113.04 Now divide this to 80%: 22608 / 113.04 = 200 So there are 200 pellets.
Thank you so much I fanned and medaled you
thank you I will fan you
tell me what you got on the test
are you in K12
