Find the exact circumference of a circle with diameter equal to 8 ft. 8 ft. 16 ft. 64 ft.
maria [59]

ANSWER

8π ft

EXPLANATION

The circumference of a circle is calculated using the formula C=πd.

Where d=8 is the diameter of the circle.

We substitute d=8 into the formula to obtain,

C=8π ft.

Because we are looking for the exact circumference, we leave the answer in terms of π.

7nadin3 [17]
So we can get from these two equations that y = 6x + 2 = 6x + 9

6x + 2 = 6x + 9
0 = 7 , but that's incorrect, so this set has no solution.

Plsssssss help<br>got 20 mins​<br>the question is: The sin of angle DCB is
Elena L [17]

Answer:

i. <DCB = 53.13^{o}

ii. Sin of <DCB = 0.8

Step-by-step explanation:

Let <DCB be represented by θ, so that;

Sin θ = \frac{opposite}{hypotenuse}

Thus from the given diagram, we have;

Sin θ = \frac{4}{5}

        = 0.8

This implies that,

θ = Sin^{-1} 0.8

   = 53.1301

θ = 53.13^{o}

Therefore, <DCB = 53.13^{o}.

So that,

Sin of <DCB = Sin 53.13^{o}

                    = 0.8

Sin of <DCB = 0.8
