Answer:
530.66 cm²
Step-by-step explanation:
First, since the formula for the area of a ball is r² x 3.14, you multiply 13 by itself. Since 13x13 is 169, you do 3.14x169. Your answer should be 530.66 cm². (i don't know what the other one is, or if it's just a separate question.)
80+x+45+2x+55=180
3x+100+80=180
3x=0
X=0
Measure of angle a=45
