π in²
Step-by-step explanation:
We'll begin by calculating the radius of the circle. This can be obtained:
Area of sector (A) = 4π in²
Angle (θ) = 120 °
Radius (r) =?
The radius of the circle can be obtained by using the formula for calculating the area of a sector. This is illustrated below:
A = θ/360 × πr²
4π = 120/360 × πr²
4π = ⅓ × πr²
Cross multiply
3 × 4π = πr²
12π = πr²
Divide both side by π
r² = 12π / π
r² = 12
Take the square root of both side
r = √12 in
Thus, the radius is √12 in.
Finally, we shall determine the area of the sector created by 30 °. This can be obtained as follow:
Radius (r) = √12 in
Angle (θ) = 30 °
Area of sector (A) = ?
A = θ/360 × πr²
A = 30/360 × π(√12)²
A = 1/12 × 12π
A = π in²
Therefore, the area of the sector created by 30 ° us π in².
