Please help and explain too

Radius = 5inch

CD = 2.75 cm

Step-by-step explanation:

A) isosceles triangles AC = AD  BC = BD  BC = AC you join lines up and then do Pythagoras.  AC ² =  1/2 * 8 ²  +  1/2 6²

AC² = 4sq + 3sq

25sq = 16sq + 9sq

AC² = 25sq = 5inch

Radius = 5inch

B) AB = 8inch  CD = 6inch  radius = 5  ratio = 4 : 3 : 2.5

AB = 24cm CD =  18  radius = 13cm  ratio = 4 : 3 : 2.1

4- 2.1 = 1.9   1.9 distributed = 1.30 + 0.65 + 1 =2.75

so ratio must be 4: 2.75 : 2.1 = 4 : 3 : 2.5

Therefore CD = 2.75 cm

Just to get you started.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

46 dollars is the answer.
