√30 = 5.47722557505

so 5.5ft × 5.5ft ≈ 30ft²

Answer:

C. 21.98

Step-by-step explanation:

In this case, you would have to multiply 3.14 times 7. If you didn't have the diameter, and all you had was the radius, you had find half of seven, which is 3.5, multiply that by 2, and finally multiply that answer by 3.14. Hope this helps! Have a nice day :D

Secant RM intersects secant RN at point R. Find the length of RQ. If necessary, round to the hundredths place.

Answer:

3 Units

Step-by-step explanation:

Secant RM intersects secant RN at point R.

The secants intersects the circle at points P and Q respectively as seen in the diagram.

To determine the length of RQ, we use the Theorem of Intersecting Secants.

Applying this on the diagram, we have:

RP x RN=RQ X RM

4(4+5)=RQ(RQ+9)

Let the length of RQ=x

$4*9=x^2+9x\\36=x^2+9x\\x^2+9x-36=0\\x^2+12x-3x-36=0\\x(x+12)-3(x+12)=0\\(x+12)(x-3)=0\\x+12=0$ x-3=0\\x=-12 or x=3\\Since x cannot be negative$\\x=|RQ|=3$
