Convertir elemento a fracción: 1 = 1/1
Mínimo común múltiplo de 1,5,3 = 15
Ajustar fracciones según el mcm
Dado que los denominadores son iguales, combine las fracciones:
Sumar Restar los números: -15 + 21 + 10 = 16
The radius of this circle is (B) 4.9 cm.
<h3>To find the radius of the circle:</h3>To solve this problem, we need to, first of all, convert the angle from radians to degrees.
data;
- length of an arc = 18cm
- angle = 7/6π rads
- π= 3.14
Length of an Arc:
The formula for the length of an arc is given:
θ/360 ×
Let's substitute the values and solve:
From the calculations above, the radius of this circle is 4.9cm.
Therefore, the radius of this circle is (B) 4.9 cm.
