Answer:
24416.64 cubic centimeters
Step-by-step explanation:
The equation for the volume of a sphere is
. The radius given is 18cm and we are instructed to use 3.14 instead of pi, so our equation will be
. Once this is multiplied out, we see that the volume of the sphere is 24416.64 cubic centimeters.
Hope this helps! :)
The first number in this item can be also expressed as 2.3 x 10³. Now, dividing the numbers 2.3 and 0.4 will give us an answer of 5.75. There exists a rule which states that when two similar numbers are divided only having different exponents, their exponents should be subtracted. The final answer to this item is therefore,
5.75 x 10¹¹
1.The temperature will be, T2= 169.8 K
2. The volume if the temperature is 318 K is 0.170 L
<h3>What is Charles Law?</h3>
Charles's law, a statement that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant.
Given: V1= 250 ml=0.25L
V2=150 ml= 0.15 L
T1= 10 °C=283 K, T2=?
Now using Charles law
V1/T1=V2/T2
0.25/283=0.15/T2
T2= 169.8 K
2. T1= 20 °C= 293 K
V1= 160 cm³
T2= 318 K
V2=?
Using Charles Law,
V1/T1=V2/T2
0.16/293=V2/313
0.170 L=V2
