#16 write the equation of the circle

need

equation of circle is given as

where (h,k) is center of cirlce and r is radius.

so lets figure out it from graph.

as we can see in graph center is at ( -1, 1)

radius is 4 units as shown in graph but we can calculate it. take any point on circle and calculate its distance from center. lets take point (3, 1)

now distance = √((3+1)^2+(1-1)^2)

= √16 = 4

lets put it in equation

(x +1)^2 + (y-1)^2 = 4^2

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36

idk
