3pi+8(t-pi)-4t
=3pi+8t-8pi-4t
=-5pi+4t
the formula for the circumference of a circle is
<span>C = 2 × π × r or C = π × D </span>
<span>If either r or D is known, you can calculate the circumference by simply substituting the known value for r or D in the formula. Use 3.14 for π.
</span>RADIUS = 10DIAMETER = 20
C IS THE ANSWER
Answer:
2827.433
Step-by-step explanation:
First start with the volume of a sphere and use the given volume to solve for the radius r.
So the radius of this sphere is 15 inches.
Now we use this radius to find the surface area
And then you get 2827.433
Answer:
3.5%
Step-by-step explanation:
In this case, the final probability would be the product of the two probabilities that the plating shows us:
First probability would be:
We are told that three quarters of the equipment (3/4) in the laboratory and the other quarter (1/4) near the pond, we are interested in the latter, that is, the probability is 1/4 = 0.25
Second probability:
We are told that 14% collected insects, therefore it would be 0.14
The final product is the question they ask us:
0.25 * 0.14 = 0.035
Which means that the joint probability is 3.5%
