The third one I think so ....
Answer:
2.5 + 3(5-2.1p) = -13.37
2.5+15-6.3p=-13.37
17.5-6.3p=-13.37
-6.3p=-30.87
p=4.9
hope this helps
have a good day :)

Step-by-step explanation:
Answer:
About 131.95 (you may have to round up)
Step-by-step explanation:
Volume of a cone = pi(r^2)(h/3)
= pi(3^2)(14/3)
= pi(9)(4 & 4/5)
= pi(43.2)
If your teacher wants an exact number, you have to multiply 43.2 y whatever your teacher says to shorten pi to, usually 3.14. The about 131.95 is from 43.2*3.14 I think.
