Answer:
90
Step-by-step explanation:
DM=1/4 of MBND
a circle =360
360÷4=90
Supplementary means the 2 angles add up to 180 so...
124+(2x+4)=180
124+2x+4=180
124+2x+4-4=180-4
124+2x=176
124-124+2x=176-124
2x=52
2x/2=52/2
x=26
plug in and check
124+2x+4=180
124+2 (26)+4=180
124+52+4=180
176+4=180
180=180
If 9 is the radius and 20 is the height then it would be 5089.4 cm^3
