Answer:
∠COA = 160°
Step-by-step explanation:
The angle intercepted on opposite side of the circle from an ARC has a measure of HALF of the Arc.
∠CBA is HALF of the ARC CA
∠CBA is given as 80°
So Arc CA is 80 * 2 = 160°
Now,
∠COA is an intercepted angle that is at the CENTER. This angle has same measure as the Arc it is intercepted from (Arc CA).
Hence,
∠COA = Arc CA
<u>∠COA = 160°</u>
Answer:
12.79%
Step-by-step explanation:
Let :
Great grand mother = 86 years
Jenny = 11 years
Let the percentage = x
x % of great grandmother's age = Jenny's age
x% * 86 = 11
x/ 100 * 86 = 11
86x / 100 = 11
86x = 100 * 11
86x = 1100
x = 1100/86
x = 12.79
x = 12.79%

<h3>Answer:</h3>
We know that,
Volume of cone = 1/3πr²h
- 1/3 × π × (7)² × 9
- 49 × 3π
- 147π inches³
So. <u>Correct choice</u> - [B] 147π inches³
