You have little to no information here but i assume you are using the apex program and the only spiral i know of is made up of 45 right triangles if you have more information im glad to help sorry dude
Answer:
false. it must be
(x - 5)^2 + (y - 4)^2 = 9
Square the base, height and hypotenuse
add the base and height together and if it equals the hypotenuse it is a right triangle
example:
base = 3, height = 4, hypotenuse = 5
3^2 + 4^2 = 9 + 16 = 25
5^2 = 25
25 = 25 so that would be a right triangle.
Its 114.2 because the area of the full circle is 200.96. So you take that divided by 4 +the area of the square(64)
the equation looks like this: 3.14×64÷4=50.24
then 50.24+64=114.2
