Answer:
Step-by-step explanation:
Since, The total number of student = 300
Out of which,
The number of students who are only in Maths = 120
And, The number of students who are only in Science = 50
While, the students who are not from any subject = 100
Hence, the number of student who are from both maths and science = Total student - Maths student (only) - science student (only) - None
= 300 - 120 - 50 - 100
= 30
That is, there are 30 students who are both from science and maths,
Thus, the probability of selecting one student who is both from maths and science = 30/300 = 1/10
The diameter of the cylindrical rain barrel which Sophie bought to water her garden, and want to build a platform for it is 15 in.
<h3>What is of volume of cylinder?</h3>Volume of cylinder is the amount of quantity, which is obtained by it in the 3 dimensional space.
The volume of the cylinder can be given as,
Here, (r) is the radius of the base of the cylinder and (h) is the height of the cylinder.
Sophie bought a cylindrical rain barrel to water her garden, but she forgot to ask the seller what the diameter of the barrel was.
She needs to know the diameter so that she can build a platform for it to sit on.
The seller told her the volume of the barrel is 6,925pi cubic in and its height is 38 in.
The diameter of the cylinder is twice the radius of it. Thus, the diameter of the cylinder is,
Thus, the diameter of the cylindrical rain barrel which Sophie bought to water her garden, and want to build a platform for it is 15 in.
