Answer:
116
Step-by-step explanation:
Area of Circle is .
There are two circles in this question. 1 is the large circle with radius 6.5cm and the smaller circle with radius of 2.3cm.
Area of shaded area = Area of large circle - area of small circle
∴
Area of shaded =
Area of shaded
(3 significant figures)
116 cm²
The shaded area = outer area - inner area
outer area = πr² ( with r = 6.5 ), thus
outer area = π × 6.5² = 42.25π cm²
inner area = πr² ( with r = 2.3 ), thus
inner area = 5.29π cm²
Thus
shaded area = 42.25π - 5.29π = 36.96π ≈ 116 cm² (to 3 significant figures )
Answer: 12%
hi
the answer is A:)
y= 3×-6
put y = 0
0= 3x- 6
3 X = 6
X=-2
so the point is (2, 0 )
