2×8=16
The length of line AB in the intersecting chords is determined as 16 units.
What is the length of AB?The length of line AB is calculated by applying intersecting chord theorem as follows;
The radius of the circle = 10
Applying Pythagorean theorem as follows;
EB² + 6²= r²
where;
r is the radius of the circle = 10EB² + 6²= 10²
EB² = 10² - 6²
EB² = 100 - 36
EB²= 64
EB = √ 64
EB = 8
Since EB is the half of length AB, then the value of the length AB is calculated as;
AB = 2 x 8
AB = 16 units

Smaller circle C is inside larger circle C. The smaller circle is labeled the garden. The radius of the smaller circle is 8 feet. The distance from the rim of the inner circle to the rim of the outer circle is 3 feet. A circular garden with a radius of 8 feet is surrounded by a circular path with a width of 3 feet. What is the approximate area of the path alone? Use 3.14 for Pi. 172.70 ft2 178.98 ft2 200.96 ft2 379.94 ft2
Answer:
178.98 ft2
Step-by-step explanation:
The approximate area of the path is 179 ft².
Area of the smaller circleThe area of the smaller circle is calculated as follows;
A₁ = πr₁²
Where;
r₁ is the radius of the smaller circle = 8 ftA₁ = π x 8²
A₁ = 201.088 ft²
Area of the bigger circleA = πr₂²
Where;
r₂ is the radius of the bigger circle = 8 + 3 = 11 ftA₂ = π x (11)²
A₂ = 380.18 ft²
Area of the pathA = A₂ - A₁
A = 380.182 ft² - 201.088 ft²
A = 179.094 ft²
Thus, the approximate area of the path is 179 ft².

Se tienen cuatro libros de Matemáticas, tres Biología y tres Religión ¿De cuántas maneras diferentes se pueden ordenar todos los libros en línea recta?
Answer:
4,200
Step-by-step explanation:
Tenemos un total de:
4 libros de matemáticas
3 libros de biología
3 libros de religión
10 libros en total.
Ahora vamos a contar la cantidad de opciones que tenemos para cada posicion.
Primer libro (tenemos 10 opciones)
segundo libro (tenemos 9 opciones, porque ya colocamos un libro)
tercer libro (tenemos 8 opciones, porque ya colocamos dos libros)
Con esto ya podemos estimar el número de opciones para cada posicion, y sabemos que el número total de combinaciones es igual al producto entre los números de opciones para cada caso. El número total de combinaciones es:
C = 10*9*8*7*6*5*4*3*2*1 = 10!
Ahora si asumimos que no podemos diferenciar los libros de matemáticas, entonces no debemos contar sus permutaciones (si tenemos 4 libros de matemáticas, tenemos 4*3*2*1 permutaciones = 4! permutaciones). Debemos dividir al numero total de combinaciones por 4!.
Y lo mismo pasa para las 3! permutaciones de los libros de biología y las 3! permutaciones de los libros de religión.
Entonces el número total de combinaciones diferentes es:
[tex]C = \frac{10!}{3!*4!*3!} = \frac{10*9*8*7*6*5*4*3*2*1}{(3*2*1)*(4*3*2*1)*(3*2*1)} = 4,200[/tex]
Hay 4200 diferentes formas de ordenar los libros.
