Sagot :
Step-by-step explanation:
Area of a circle = πr^2
Area of a sector with angle x° = (x/360) πr^2
Just use that formula:
x = 81°
r = 8.91 cm
Required area of sector = (81/360) × π × 8.91^2 = 56.116 cm^2
To the nearest tenth, Area = 56.1 cm^2
Answer:
56.1
Step-by-step explanation:
Area of sector = (Ф/360)πr²
where r = radius and Ф = central angle
It appears that the radius is 8.91 and the central angle is 81°
So we have Area = (Ф/360)πr² and r = 8.91 and Ф = 81
==> plug in values
area = (81/360)π(8.91)²
==> evaluate the exponent
area = (81/360)π79.3881
==> multiply 79.3881 and π
area = (81/360)249.41
==> multiply 249.41 and (81/360)
area = 56.1
