Best to look up the formula for the surface area of a sphere and then find it:
A = 4πr^2, where r is the radius of the sphere. Then,
A = 4π(15 in)^2 = 4(3.14)(225 in^2) = 2826 in^2 (answer)
This is represented by the formula given in the lower left.
Answer:
There are two types of similar triangle problems; these are problems that require you to prove whether a given set of triangles are similar and those that require you to calculate the missing angles and side lengths of similar triangles. Subtract both sides by 130°. Hence; By Angle-Angle (AA) rule, ΔPQR~ΔXYZ.

1-12 is between 5/6 and 13.
6/6 is after 5/6 and that just equals 1
1. its 23, because if you were to substitute 5 for x, 7(5) = 35 and if you were to substitute -3 for y, 4(-3) = -12. Therefore, 35 + -12 = 23.
