To find the area of the circle with diameter = 18 cm
We will use the formula:
where r= radius of the circle
From the quesion diameter = 18 cm
radius = diameter/2
radius = 18cm/2 = 9 cm
substituting r = 9cm into the formula
The above answer is when we are to leave the answer in terms of π
Otherwise if π is given to be 3.14 or 22/7 , we will simply substitute into the formula
That is given that π= 3.14

Answer:
-26 is your answer
Step-by-step explanation: 2³ first which = 8 then solve in the parenthesis and all inside parenthesis = -19 so now you have -19+9-4². Now, solve 4² which = 16 so now you have -19+9-16 then solve that and it should give you -26.

Answer:
+5x+6.
Step-by-step explanation:
Here you can use the foil method.
1. Multiply x by x to get .
2. Multiply x by 3 to get 3x.
3. Multiply 2 by x to get 2x.
4. Multiply 2 by 3 to get 6.
Now, you have to add all those terms to get +3x+2x+6 and you can simplify that to +5x+6.
