Easy
the radius is the distance from the center to a point on the circle
we are given
center=(7,1)
a point=(8,7)
find the distance
distance formula
D=

so the distance between point and center is radius
D=

D=

D=

D=√37 units
radius is √37 units
D) (X,Y) <span> → (x + 4, y - 5).

We find the area of all the faces and add those up
So
Total area = (12*5) + 2(1/2 *3 *4 ) + (4*12)+(3*12)
= 60 + 12 + 48 + 36
= 156 square feet
third option is the correct one
