Answer: It represents the area of the two circular sides ("lids")
Explanation:
Imagine you made a cylinder out of 3 pieces of paper. The cylinder can be decomposed into two circular shapes (radius r) and one rectangular piece with two side lengths: one is "h", the other has to be long enough to go around each of the disks, so it has to be 2*pi*r long.
So the term 2*pi*r*h is the area of the rectangular piece and pi*r^2 is the area of each of the "lids" Since there are two of those, the term 2*pi*r^2 represents the area of the bottom and top lids.
Answer:£24
Step-by-step explanation:
Let the total money be represented by Y
Total ratio =1+2=3
Krutika's share =1/3 × Y
8= 1/3×Y
Y=8÷(1/3)
Y= 8×3
Y=£24
The total Money they won was 24
Answer:
4. Slope of function B = -slope of function A
Step-by-step explanation:
Given:
Function A is given as:

The above equation is of the form
, where
represents slope of the line.
Therefore, on comparing the function A with the above standard form, er conclude that, slope of function A is -2.
Now, from the graph of function, we consider any two points on the graph and determine the slope of the line using the two points.
Let us consider the points 
Now, the slope of the line passing through these two points is given as:

Therefore, slope of function B is 2.
Therefore, the correct relation between the slopes of the two functions is that the slope of function B is negative of the slope of function A.

Step-by-step explanation:
A circumcenter is the point where the perpendicular bisectors of a triangle intersect.
This means
Since BC = 24 units, then BD = 12 units (half of BC).
Since FA = 8 units, AB = 16 units (twice FA).
Consider right triangle BGF. In this triangle, BF = 8 units (congruent to FA), BG = 13 units. By the Pythagorean theorem,
Triangles BFG and AFG are congruent right triangles, then BG = AG. In right triangle AGE,
units,
units. By the Pythagorean theorem,
