Answer:
r=2.9 cm
Step-by-step explanation:
Given:
volume=486π cm^3
height=18 cm
volume of a cone=πr^2h
486=π*r^2*18
486=18π*r^2
486/18=πr^2
27/π=r^2
27/3.14=r
8.5987=r^2
=r
2.9323 =r
2.9=r(after converting to nearest tenth)
Answer:
A real world scenario of the pythogorean theorem would be for example, a soccer player trying to see if going across the field or along it is faster. Or for example, a builder trying to make a triangular roof for a house.
I don’t really know? What grade is this?
Answer:
116°
Step-by-step explanation:
In a triangle, the sum of all interior angles is 180°
<PRS + <RSP + <SPR = 180°
51° + <RSP + 65° = 180°
<RSP = 180° - 65° - 51° = 180° - 116° = 64°
Since, <PST and <RSP are supplementary angles,
<PST + <RSP = 180°
<PST = 180° - 64° = 116°
