Circumference = 2 · π · r or π · d
Radius = 7.8
7.8 × 2 = 15.6
15.6 × 3.14(π) = 48.984
Circumference = 48.984 rounded = 49
Area = π · r²
Radius = 7.8
7.8 × 7.8 = 60.84
60.84 × 3.14(π) = 191.0376
Area = 191.0376 rounded = 191
Hope this helped☺☺
Answer:
{x| x≤ 1/2 or x ≥ 3/4}
Step-by-step explanation:
The values of x that make the factors zero are 3/4 and 1/2. The product of these factors will be positive when both factors are negative (for x < 1/2) or when both factors are positive (x > 3/4). The matching answer selection is the third one.

Hello!</h3>
In order to find the vertex of a parabola, we use the following formula:
Remember, a parabola looks like so:
Now we know what a and b stand for.
In this case, b is -4, and a is -1:
Simplify:
Divide:

<span>If you take twenty seven and divide by sixty you get 0.45. So the equation 27/60=0.45 would show that the fastest human ever was running at a speed of 0.45 miles every minute. .</span>
