Volume & surface area of spheres


We talked about Volume & Surface Area of Sphere
what we did today is do some questions about volume and surface area, we also looked over the Conversion Table witch showed different measurements converted to other measurements, but the one's that we mostly looked at were 1 inch = 2.54 cm, and 1 mile = 1.61 km.

We first got put in groups of 3 and worked on the questions together.

One question that we did was " A car handbook calls for the oil to be changed every 5000 km, how many miles is that ?

( 1 km = 0.621 mi )

what i did was i used the hint that they gave, and i changed the 1 km to 5000 km, then i multiplied it by 0.621 mi, because every 1 km = 0.621 mi. So then i got 3105 mi for how many miles it had to be before changing it.

When we were done doing the questions, we also got an assignment to do for home work, witch was Pg. 34 and questions # 1 - 5.
