This is my work and only part 1
Answer:
201.1 meters squared
Step-by-step explanation:
A= pi*r squared
Diameter= 16, to find the radius we must divide by 2
16/2=8
Radius= 8
A= pi* (8)^2
A= 201.06
The area of the circle is 201.1 meters squared.
12x^3-11x^2+9x+18 divided by 4x+3
put he division into fraction
12x^3-11x^2+9x+18/4 x +3
reduced fraction by 2
12x^3-11x^2+9x+9/2 x +3
calculate sum
12x^3-11x^2+27/2 x +3
that is your answer ^
hope this helps :)
