What are you even trying to find? You didn't even include it in your question.

Step-by-step explanation:

A)

120 + 30 + 90 = 240

60/240 = 1/4

given pi value= 3

radius=7

we know,

area of a circle(A)= πr²

= 3×7²

=147cm²

you would use the form y2-y1/x2-x1 so in this case it would be 3-0/2+4 which would be 3/6 but simplify your answer and you get would be 1/2 so your answer is 1/2
