Step-by-step explanation:

Hi everyone! I have a question!
Tju [1.3M]

Answer:

7π

Step-by-step explanation:

SO first find the area of the whole circle

which has a radius of 3

a=πr^2

So 3^2=9

9π

Now the two circles which are the same in area due to having the same radius

so if you plug in the 1 for radius the answer would just be π or 1π

now multiply that by 2 becuase there are 2 identical circles

π*2=2π

Now subtract

9π-2π=7π

Help!!! I don’t understand how to do this
Olegator [25]

Answer:

85 degrees

Step-by-step explanation:

the sum of supplementary angles=180

155+ angle in the triangle=180

angle=180-155

angle=25 degrees

the sum of angles of triangle=180

25+60+x=180

85+x(inside triangle)=180

x=180-85

x=95

angle with (?):

the sum of supplementary angles=180

95+(?)=180

(?)=180-95

(?)=85 (An exterior angle of a triangle is equal to the sum of the opposite interior angles)
