The height of the cylinder is 18 meters and the volume of the cylinder is 4,374 cubic meters. What is the area of the base of the cylinder?
Answers
Answer:
242.76m^2
Step-by-step explanation:
Given data
Height=18m
Volume=4,374m^3
We know that the expression for the volume of a cylinder is
V=πr^2h
substitute
4374=3.142*r^2*18
4374=56.556*r^2
4374/56.556=r^2
77.339=r^2
r=√77.339
r= 8.79m
But the area of a circle is expressed as
A= πr^2
A=3.142*8.79^2
A=3.142*77.2641
A=242.76m^2
Hence the area of the base is 242.76m^2

You have two decks of cards and you select a card from each deck. What is the probability to selecting a jack both times?
Answers
Answer:
The probability is 1/13 (1 to 13).
Step-by-step explanation:
In a card deck, there are 52 cards with 4 Jacks. If you simplified this probability, the answer would be 1 to 13.
4/52 = 1/13
In two card decks, there are 104 cards with 8 jacks. If you simplified this probability, the answer would also be 1 to 13.
8/104 = 1/13
