66 will be the area because triangle DEF is increased by 8 feet so that means the height will be 11. So 11 times 12 divided by 2 is 66
Answer:
no its C (sorry if I'm wrong but I'm pretty sure its right)
Consider the cup a cylinder. The formula for the volume of a cylinder is: V= PI x r^2 x h
Cup A: 3.14 x 7 x 1.5^2 = 49.46
This is large enough
Cup B: 3.14 x 5 x 1^2 = 15.7
This is too small
Cup C: 3.14 x 6 x 1.25^2 = 29.44
This is too small.
Answer:
20 students in science class, 25 in math
Step-by-step explanation:
so let 1 classroom= x
so the other classroom= x+5
if there is a total of 45 students
x+x+5=45
2x=45-5
2x=40
x=20
