Given figure is of HEXAGON.
the sum of the measures of the interior angles of a hexagon

(-$11) x 12. That would be the equation because there are 12 months, so you would multiply -11 from 12 to get -132 every year for the tennis club membership.
Answer:

Step-by-step explanation:
The volume (V) of a cylinder is
V = area of base × height
here area of base = 64π and height = 10, hence
V = 64π × 10 = 640π in³ ← exact value
Answer:
3x°
Step-by-step explanation:
when a triangle is isosceles, the angles at its base are equal.
