<h3>
Answer: Point R (choice 4)</h3>
Explanation:
Points A, C, U, D, S and E are all in the bottom floor plane. A plane is a flat surface, and saying "points are coplanar" means the points are all on the same plane.
Points like R, T and B are not on the floor plane, so they are not coplanar with the other points mentioned in the previous paragraph.
In other words, point R is not coplanar with points C, D and E since R is not on the floor plane with C,D,E.
A. The area of SHN=base*h/2= SN*HT/2=21*10/2=21*5=105 cm^2
b. Shaded area=A SMN+A SNQ - A SHN= SN*QR/2+SN*QR/2- 105 cm^2
=21*24/2+21*24/2-105 cm^2=
=504-105 cm^2=399 cm^2
As the diameter is 18, a radius is half the diamater ergo the radius is 9.
Use the circumference formula:
So, adapted it would be:
2 * π * 9 which would be 56.7.
The circumference is 57m.
Hope this helps!
