I need some help finding the volume of a sphere with a diameter of 18.6cm. The website says the answer I got from my calculator was wrong! Help would be greatly appreciated!
Answers
Answer:
Volume, V = 3367.6 cm³
Step-by-step explanation:
Given the following data;
Diameter = 18.6 cm
Radius = diameter/2 = 18.6/2 = 9.3 cm
Pie, π = 3.14
To find the volume of the sphere;
Mathematically, the volume of a sphere is given by the formula;
[tex] Volume \; of \; a \; sphere = \frac {4}{3} \pi r^{3} [/tex]
Where;
r is the radius of the sphere.
Substituting into the formula, we have;
[tex] V = \frac {4}{3} * 3.14 * 9.3^{3} [/tex]
[tex] V = 4.186666667 * 804.357 [/tex]
Volume, V = 3367.6 cm³

0.25
Answers
Answer:
0.50 :)
Step-by-step explanation:
The probability of the union of being either a freshman or junior is 0.50
What is probability?"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."
Formula of the probability of an event A is:P(A) = n(A)/n(S)
where, n(A) is the number of favorable outcomes,
n(S) is the total number of events in the sample space.
For given example,
Students have equal probabilities of being freshmen, sophomores, juniors, or seniors.
⇒ P(freshman) = 0.25
⇒ P(sophomores) = 0.25
⇒ P(juniors) = 0.25
⇒ P(seniors) = 0.25
We know for event A and B,
P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
Assuming event A : student is a freshman
event B : student is junior
P(A) = 0.25
P(B) = 0.25
The number of students who are freshman as well as junior = 0
⇒ n(A ∩ B) = 0
⇒ P(A ∩ B) = 0
Now, the probability of the union of being either a freshman or junior would be,
⇒ P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
⇒ P(A ∪ B) = 0.25 + 0.25 - 0
⇒ P(A ∪ B) = 0.50
Therefore, the probability of the union of being either a freshman or junior is 0.50

A rectangle has vertices (a,b), (c,b), and (a,c). Find the fourth vertex.
Answers
Answer:
Step-by-step explanation:
Abc
The required coordinate of the fourth vertex is (c, c).
What is coordinate?Coordinate, is represented as the values on the x-axis and y-axis of the graph. while the coordinate x is called abscissa and the coordinate of the y is called ordinate.
here,
A rectangle has vertices (a,b), (c,b), and (a,c)
let the vertex of the first coordinate be [x, y],
Now,
for side a Corrdiante A (a, b) and B (c , b)
Now, coordinate the opposite side C(a, c) and D(x , y)
The coordinates of D must be equal to x coordinate of B and y ordinate of C so,
D(x, y) = D(c, c)
Thus, the required coordinate of the fourth vertex is (c, c).

Luis's math teacher plots student grades on their weekly quizzes against the number
of hours they say they study on the pair of coordinate axes and then draws the line of
best fit. What is the meaning of the x-value on the line when y = 75?
Answers
Answer:
In the graph, we have a linear fit of the student's grades as a function of the number of hours they say that they study.
Then the y-axis represents the grade, and the x-axis represents the number of hours of study, and because this is a linear fit, we will have something like:
y = a*x +b
If we input a value of x here (number of hours studied) we would get the expected grade for the weekly quiz y.
In this situation, the meaning of the x-value on the line when y = 75 would be the (adjusted) number of hours studied to get a grade of 75.
So this x-value is the average number of hours that a student needs to study to get a grade of 75 points.

AC × cos15° = 9.2 ( divide both sides by cos15° )

The ratio of the number of Baskin Robbins :Cold stone ice cream cones sold in a day is 11:9.If the number of Baskin Robbins cone sold is 44 .(a)How many cold stone cones are sold ? (b)If the number of cold stone cones on the next day is reduced to 20.what is the new ratio?
pls answer fast plsssssssssss
Answers
Answer: A. 36
B. 5:11
Step-by-step explanation:
(a)How many cold stone cones are sold?
Let the number of stone colds sold be represented by x.
Therefore, we can form an equation as:
11/9 = 44/x
Cross multiply
11 × x = 44 × 9
x = (44 × 9)/11
x = 36
The number of stone cold sold are 36.
(b)If the number of cold stone cones on the next day is reduced to 20.what is the new ratio?
The new ratio will be gotten as:
= 20/44
= 5/11
= 5:11
The ratio is 5:11
