Answer:

a = 150

Step-by-step explanation:

A octagon is 1080 degrees. The half circles are showing which angles are the same. So all the red circles are 120 degrees. To find the green circles, multiply 120 by 4 for the total of the four angles and then subtract it from 1080:

120(4) = 480

1080 - 480 = 600

So 600 is the total of all the green half circles added together, so divide 600 with 4 because there are four green half circles.

600/4 = 150

Answer:

a = 150

Step-by-step explanation:

The sum of the internal angles of an octagon is 1080°.

4a+4(120)=1080 (There are four 120^{\circ} and 4 a^{\circ}, they sum to 1080°)

4a + 480 = 1080

4a = 600

a = 150

Hope this helps :)

First you need to find how much is left in the container by finding the whole volume.
cylinder volume= πr²h where r is the radius and h is hight
V= (3.14)*(5²)*(10)
V=(31.4)(25)
V=785cm³ is the total volume
now half has been used so divide that number in half
785/2= 392.5cm³
now she uses 4cm³ a day so divide
392.5/4= 98.125
round to the nearest whole number
answer is B 98
