Answer:
Radius: 7.75
Volume: 1949.82
Step-by-step explanation:
The radius is half the diameter, so 15.5/2 is 7.75
The formula for a sphere is V=4/3 (πr^3). All that needs to be plugged in is the radius. You should be able to use a calculator for this problem, so the rounded answer is 1949.82.

Answer:
option A. 5 apples for $2.50
Step-by-step explanation:
You must find the price per apple for each option by dividing the cost in cents by the number of apples. 250 cents divided by 5 apples gives you 50 cents per apple, while option c is 55 cents per apple, option b is 60 cents per apple, and option d is 52 cents per apple.
Which point of concurrency is NOT always inside a triangle? Check all that apply. A. circumcenter B. incenter C. orthocenter D. centroid
Answers
The point of concurrency which is not always inside a triangle is circumcenter and orthocenter.
We are given that;
The four options
Now,
A point of concurrency is a single point shared by three or more lines1. In a triangle, there are four points of concurrency that are associated with different types of line segments: centroid, incenter, circumcenter and orthocenter.
The centroid is the point of concurrency of the medians of a triangle, which are the line segments that connect the midpoints of the sides to the opposite vertices. The centroid is always inside the triangle.
The incenter is the point of concurrency of the angle bisectors of the triangle, which are the line segments that divide the angles into two equal parts. The incenter is also always inside the triangle.
The circumcenter is the point of concurrency of the perpendicular bisectors of the sides of the triangle, which are the line segments that are perpendicular to the sides and pass through their midpoints.
The circumcenter can be inside or outside the triangle, depending on the type of triangle. For an acute triangle, it is inside; for a right triangle, it is at the midpoint of the hypotenuse; for an obtuse triangle, it is outside
Therefore, by triangle the answer will be circumcenter and orthocenter.

Answer:
m∠BAC = 52° or theta = 52°
Step-by-step explanation:
I am guessing that you are trying to find m∠BAC ( which is theta)
(1) The measure of an inscribed angle is 1/2 the measure of the intercepted arc
measure of arc BC is twice the measure of ∠CDB
measure of arc BC = 2(26) = 52
(2) The measure of a central angle equals the measure of the intercepted arc.
m∠BAC = 52°
Note: You need to remember statements (1) and (2) to help you with this type of problem. OK?

The graph of the given equation is attached to the solution.
What is graph?In math, a graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.
Given is an equation, 1.5x+2y = 3 we need to graph it,
So, first finding the coordinates,
1.5x+2y = 3,
Put x = 0
y = 1.5 [0, 1.5]
Put y = 0
x = 2 [2, 0]
Putting the coordinates on the graph and connect them, the line obtained will be the graph of the equation,
Since, the equation is linear the graph will be a straight line,

if a rectangular square pyramid has the square base of 3in and the height of 4 in, what is the volume?
Answers
Volume of a pyramid = Length x width x height / 3
A square base means both the length and width are the same.
Volume = 3 x 3 x 4 /3 = 12 square inches.
Answer:
12in^3
Step-by-step explanation:
v = (1/3) b^2 * H
b^2 = base length^2

Answer:
3.14 units
Step-by-step explanation:
The formula for the length of an arc is ...
s = rθ
where r is the radius of the circle, and θ is the central angle in radians.
__
The relationship between degrees and radians is ...
180° = π radians
If we divide this equation by 3, we see ...
60° = π/3 radians
__
The radius is given as 3 units, so the arc length is ...
s = (3 units)(π/3) = π units
The arc length is 3.14 units.
Find the area of each circle. Use 3.14 for the value of pi. Round your answer to the nearest tenth. Do NOT include units in your answer (ie. ft, in, km, etc.) (FR)
Answers
Answer:
12.6
Step-by-step explanation:
The equation for a circle's area is [tex]A=\pi r^2[/tex].
We can use this equation to end up with A=(3.14)4
And 3.14 times 4 is 12.56.
Then we have to round to the nearest tenth.
Therefore your answer is 12.6
