Use the formula for the surface area of a right cone:
Where 'r' is the radius and 's' is the slant height, plug in what we know(use 3.14 to approximate for pi):
Multiply and simplify exponent:
Multiply:
Add, round to the nearest whole number:
In order to find the second endpoint or a line segment given the first and the midpoint, you need to realize that the midpoint is an average of the two endpoints. Given that fact, we can derive this formula looking at x values of points A and B with midpoint M. Remember this is only looking at the x values.
(A + B)/2 = M
So if we are looking for A, we can solve for A and use this modified formula.
(A + B)/2 = M
A + B = 2M
A = 2M - B
Now we can do this with the y values of these points as well. We then have the coordinates of both parts of A.

<u>Numbers given:</u>
- <em>Total</em>: 100
- Either a cat of a fish: 70
- Cat: 46
- Cat and fish: 16
<u>Neither a cat or a fish:</u> 100 - 70 = 30
<u>Fish:</u> 70 - (46 + 16) = 70 - 62 = 8
<u>Required probabilities are:</u>
- a) P(neither) = 30/100 = 0.3
- b) P(f) = (16 + 8)/100 = 0.24
- c) P(f not c) = 8/100 = 0.08
Answer:
Here is the steps. 67.5 cm^3
Step-by-step explanation:
4.5 * 6 = 27
27 * 2.5 = 67.5
Answer:
c
Step-by-step explanation: if you remove the 0 then you get 3.27
