Answer:

1308.02cm^2

Step-by-step explanation:

Finding Radius = D/2

40.82/2 = 20.41 centimetres

Finding Area of a circle

E = πr^2

= 3.14 x 20.41^2

= 416.57 π

= π x 416.5681 = 1308.02cm^2

Answer:

y=-2/4x + (-4.5)

Step-by-step explanation:

so first we look for the slope which is rise/run.

start with the lower point and count up two.

the count to the left and you have -2/4, thats your slope.

then you chose one point, like (1,-5)

so either using point slope form y-y1=m(x-x1) or standard form y+mx+b

im going to use standard form

plug in your points like so:

y= -2/4x +b

-5= -2/4(1) +b

-5 = -1/2 + b

-5+ 1/2 = b

-4 1/2 =b

so y should equal

y=-2/4x + (-4.5)

im not sure but i hope this helps a bit

Find sin 0, where is the angle shown. Give an exact value, not a decimal approximation.

Answer:

$\displaystyle \sin\theta=\frac{12}{13}$

Step-by-step explanation:

Recall that in a right triangle, sine is the ratio of the opposite side to the hypotenuse:

$\displaystyle \sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}$

We are actually not given the opposite side in this case. However, since we know the hypotenuse and the adjacent side, we can use the Pythagorean Theorem to find the opposite side. So:

$a^2+b^2=c^2$

Let a be the adjacent side and b be the opposite side. c will be the hypotenuse.

Substitute:

$(5)^2+b^2=(13)^2$

Solve for b:

$b=\sqrt{169-25}=\sqrt{144}=12$

So, the opposite side measures 12.

Then sine will be:

$\displaystyle \sin\theta=\frac{12}{13}$
