. If a spherical Triangle on Earth has an excess of 30 degrees, find the area of this spherical triangle measured in square miles.

Question

b. If a spherical triangle on the moon has an excess of 30 degrees, find the area of this spherical triangle in sqare miles.
c. Find the ratio of the above answers to a and b.

Answer 1

area=sphericalExcessinRadians*radius^2

a. area=PI/6*re^2

b. area=PI/6*rm^2

c. (re/rm)^2

Answer 2

Confused? What does that mean?

Answer 3

I gave you the formula for area of a spherical triangle given the excess angle, and the radius of the object. re is the radius of Earth. rm is the radius of the moon.
