Answer:

a = 15

Step-by-step explanation:

The formula to solve for the above diagram is given as:

Sum of the interior angles in a circle = 360°

(10a - 4)° + (6a - 2)° + (8a + 6)° = 360°

10a - 4 + 6a - 2 + 8a + 6 = 360

24a -6 + 6 = 360°

24a = 360

a = 360/24

a = 15

Complete Question

A cylindrical vase has a diameter of 6 inches. At the bottom of the vase, there are 7 marbles, each of diameter 3 inches. The vase is filled with water up to a height of 12 inches.Which of the Following could be used to calculate the volume of water in the vase?

Answer:

V_w=  \pi (3)^2(12) - 8(4/3) \pi(1.5)^3

Step-by-step explanation:

From the question we are told that:

Diameter of vase d=6

Number of marbles n_m=7

Diameter of marbles d_m=3 inch

Height of water h_w=12

 

Generally the equation for Volume of water in cylindrical vase V_w is mathematically given by

 V_w= \pi r^2h - Volume \, of \, the\, balls

Where Volume  of  the balls V_b is

 V_b= 7(4/3) \pi r^3\\\\V_b= 7(4/3) \pi (1.5)^3

Therefore

V_w= \pi r^2h - Volume \, of \, the\, balls

V_w=  \pi (3)^2(12) - 8(4/3) \pi(1.5)^3
