Question 1120424: Monica stepped outside and began to think how fast she is moving even when she is standing still.
Assume that the earth is a sphere with a radius of 3960 miles and Monica is at a latitude of 15degreesNorth.
What is Monica's speed due solely to the rotation of the earth?
What is Monica's speed due solely to the rotation of the earth? Assume for simplicity that the earth rotates around the sun in a circle of radius 93 million miles and that there are 365.25 days in a year.
Combining the two speeds from above, give the range of speeds Monica is moving while standing still.

Question 1133463: Hello!
I need to find the volume of a regular triangular pyramid that has base edges of length 30 and height 10.
I found the volume using the formula V = ((a^(3))/(6√2)), and got 3181.9805 units^3, but it appears to be wrong.
Thanks for helping!

Question 1133462: Hello!
I need to find the surface area of a pyramid that has a rectangular base with edges of length 10 and 24. The vertex of the pyramid is directly 13 units above the center of the base.
We know that the height is 13, the length is 24, and the width is 10. I tried 751.199m^2, but is it wrong and I don't understand why.
Thanks!
