12 and 1/8, I just simplified 2/16 to 1/8
The answer is the 989 is the answer
<span>L = (0.8) T^2
T^2 = L / 0.8
T = sqrt{ L / 0.8 }
T = sqrt{ 30 / 0.8 }
T = sqrt{ 37.5 }
T = 6.1 seconds
The correct answer is D) 6.1 seconds</span>
Answer:
756π cm^3.
Step-by-step explanation:
Volume of the cone
270π = 1/3 π r^2 h
270π = 1/3 π r^2 * 10
r^2 = 270 / ( 10/3 )
r^2 = 81
r = 9 cm.
So the volume of the hemisphere = 1/2 * 4/3 * π * 9^3
= 486π cm^3.
So the volume of the whole solid = 270π + 486π
= 756 π cm^3.
It’s an exponential graph. You can tell by the way the line is curved.
