Answer:
a = 72° b = 88°
Step-by-step explanation:
We know in the cyclic quadrilateral opposite angles are supplementary so
a + 108° = 180° { being opposite angles of cyclic quadrilateral }
a = 180° - 108°
a = 72°
b + 92° = 180° { being opposite angles of cyclic quadrilateral }
b = 180° - 92°
b = 88°
Answer:
908.74
Step-by-step explanation:
The formula for the volume of a cylinder is V = h * pi * r^2
h is height, r is radius, and pi is 3.14. The radius is half of the diameter, so that would make the radius 5.25.
So now plug it into the formula:
V = 10.5 * pi * (5.25)^2
= 908.74
