Answer:
1936 π square units
Step-by-step explanation:
Given the information:
<em>The circumference of a great circle of a sphere is 44π.</em>
As we know the formula used to find a circle's circumference is:
C = 2πr , where r is the radius of the circle
In this situation, we know C = 44π
<=> 2πr = 44π
<=> r = 22 units
Hence, the Surface Area of the sphere
S.A = 4π
= 4π
= 1936 π square units
While rotations, translations and reflexions do not alter the volume of the matter, dilation does increases the volume.
So the answer would be, dilation increases the volume while other types of transformations do not.
Answer:
-3.786 × 10^7
Step-by-step explanation:
Put an decimal behind a number 1-10
but keep the negative sign
so you should get
-3.7860000
Then you count how many numbers are to the right of the decimal which is 7.
That number will become the exponent and then you take away the zeros
You should then have
-3.786 × 10^7 as your answer.
First of all, remember what the equation of a line is:
Where:
m=slope
b=y-intercept.
Given this information, we can start by plugging in what we know, we are given the slope which is 2 so we can fill that in, remember m=slope
To find b, think about what your (x,y) point means:<span>(14,3). When x of the line is 14, y of the line must be 3.
Because we were given the point (14,3)
</span>
We need to find the value of b. The 2 is already set and x and y are variables. We want the equation for the line that specifically passes through the given point (14,3).
<span>Plug in for x the number 14 and for y the number 3:
</span>(14,3).
y=mx+b or 3=2 × 14+b,
solving for b: b=3-(2)(14). b=-25.
<span>Plug that in for b:
</span><span>y=2x-25
<span>Final answer:
</span><span>y=2x-25</span></span><span><span>
</span></span>
