Answer:
20,000
Step-by-step explanation:3 days= 5000 so each 3 days 5000 burns down for 12 days so 5000 x 4
Answer:
157.1 in³
Step-by-step explanation:
In order to solve this question, we need to know the volume of that cylindrical container and the volume of the sphere( this is to know the capacity of the cylinder ie how much it can take and the amount of space the sphere can occupy).
Volume of a cylinder is=
pi × r² × h
Volume of a sphere is
4/3 × pi × r²
And here we were given the radius of the cylindrical container as 5 inches and its height as 10 inches
The radius of the sphere is 1 inch.
Applying this in the formula we have,
For cylinder :
22/7 × 5² × 10 = 785.7 in³
For the sphere:
4 ÷ 3 × 22/7 × 1² = 4.19 in³
And if there are 150 marbles in the container ,it is going to occupy a total space of 628.57 in³.
Therefore,the remaining space left in the cylinder will be 785.7 - 628.57 = 157.1 in³
The answer for this question, to the correct significant digits, would
be 39 feet squared. This can be worked out in the following way: S=a*a
ft^2S=6.25*6.25S=39.0625?39.1 9and then round this up to find the answer
of 39 square feet)
Step-by-step explanation:
sec² x − 2 = 0
sec² x = 2
cos² x = ½
cos x = ±√½
x = π/4, 3π/4, 5π/4, 7π/4
