Answer:
Hey,
so first off we need to know our equation for the area of a circle;
A=πr2
So know we plug in what we already know,
sense the diamiter we can figure out the radius (half way across) by simply dividing 18 units by 2 which is 9.
Now we have
A=π9²
That is your answer π9²
One kilo is larger since one Centimeter is about the size of a pop-off eraser of your led pencil, while one Kilo is about 100,000 Centimeters.
A. 13:7 (there are a total of 13 apples and 7 red apples)

Step-by-step explanation:
8x-10=3x+90
=5x=100
=x=20
therefore
B=3(20)+90
150°
Answer:
option a is the answer
Step-by-step explanation:
put the value of x in each expression as x = -2
you'll see that in option a the expression becomes
which is not defined. hence -2 is excluded value
