Answer:
Step-by-step explanation:
10 = r²h
(2r)²(2h) = 16r²h
volume of B is 1.6 times the volume of A
The probability of drawing a black marble is 7/31 or .226 or 22.581%. To find the probability of these type of questions, add all together to get 31, then since there are 7 black marbles the probability would be 7/31.
16cm
Dividing 81.9 cm^2 by 4.9cm will give you about a 16 cm height.
:) Good Luck
15 i am pretty sure i’m probably gonna be wrong
28°
a triangle = 180°
180°-140°= 40°
180°-68°= 112°
180°-112°-40°= 28°
