The exact circumference is 60ft
Answer:
4372/1000
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Drop an altitude. Either of the two resulting right triangles with legs of length 5 and x and a hypotenuse of 10.
By the Pythagorean theorem, it follows that the answer is B.
Answer:
Step-by-step explanation:
let x represent the number
9x + 60 = 10x - 2
60 + 2 = 10x - 9x
62 = x <===
The radius of the sector is 10.27 miles
<h3>How to find the radius of a sector?</h3>
The area of a sector can be represented as follows;
area of a sector = ∅ / 360 × πr²
where
- r = radius
- ∅ = central angle
Therefore,
∅= 25 degrees
area of the sector = 23 miles²
area of a sector = ∅ / 360 × πr²
23 = 25 / 360 × πr²
cross multiply
23 × 360 = 25πr²
8280 = 25πr²
divide both sides by 25
πr² = 8280 / 25
πr² = 331.2
r² = 331.2 / 3.14
r² = 105.477707006
r = √105.477707006
r = 10.2702336877 miles
Therefore, the radius of the sector is 10.27 miles
