Answer:
1390 cm^3
Step-by-step explanation:
9 x 7 x 10 = 630 cm^3 for the rectang prism top
area * 10 for the bottom
8 x ( 12 + 7)/2 * 10 = 760 cm^3 for the trap base
total = 1390 cm^3
Answer: 30.8
Step-by-step explanation:
BE is parallel to CD, therefore, m∠BEC=m∠ECD, therefore mBC=mDE
BE is the diameter, so Arc BE is 180 degree
mBC+mCD+mDE=180
replace mCD with 3mBC, and replace mDE with mBC: mBC+3mBC+mBC=180
5mBC=180
mBC=180/5=36
mCD=3mBC=3*36=108
the inscirbed angle m∠ECD= the measure of arc DE=36
