Do Area = (base 1 + base2) × H
131.88 or jus do radius times 2 so 21+ 21 = 42.
42 x pi(3.14) = 131.88
The equation of a cricle is
h being the x coordinate of the given point and k being the y coordinate of the given point (r also being the radius).
Now we have to plug the points into the equation
now just simplify the the equation
Answer:
22x^2-20x+21
Step-by-step explanation:
thats if you meant x^2-10x+21x^2-21
