Step-by-step explanation:
Answer:
The diameter of the circle would be: 6.4 cm. rounded or 6.36619772 cm.
The radius of the circle would be: 3.2 cm. rounded or 3.18309886 cm.
Step-by-step explanation:
<h3>The diameter can be solved using: D =

</h3>
So, the first step would be : D = 
Then : D = 20 ÷ 
Finally, the answer will be : 6.36619772 cm. or 6.4 cm.
<h3>The Radius can be Solved using: r =

</h3>
The first step would be : r = 
Then : 20 ÷ 6.2831853071796 (2
)
Finally, the answer will be : 3.18309886 cm. or 3.2 cm.

Answer:
6y + 30
Step-by-step explanation:
<u>Step 1: Distribute</u>
6(y + 5)
6y + 30
Answer: 6y + 30
<u>Answer</u>
48
<u>Explanation</u>
The product of the secant and the extension of the chord is normally equivalent to square of the tangent.
From the diagram given,
The length of the secant = 2+6
= 8
Length of the extension of the chord = 6
length of the tangent = x
∴ x² = 8 × 6
= 48
