Given:
The graph of a function.
To find:
The domain and range of the given graph.
Solution:
Domain is the set of x-values or input values.
From the given graph it is clear that, the graph is defined for the interval (-4,4).
But there is a closed circle at x = -4 and an open circle at x = 4. It means, -4 is included and 4 is not included in the solution set.
Domain: [-4,4)
Domain:
Range is the set of y-values or output values.
From the given graph it is clear that, the output values are lie in the interval (-3,4).
But there closed circle at x = -3 and x = 4. It means, -3 and 4 are is included in the set of output values.
Range: [-3,4]
Range:
Therefore, domain is and range is
.
Answer:
1. = 3.143
2. Circumference
3. Area of the circle is 3850 .
ii. Circumference of the circle is 220 cm.
Step-by-step explanation:
The area, A, and the circumference, c, of a circle can be determined respectively by:
A =
C = 2r
where r is the radius of the circle.
1. the ratio of the circumference and diameter, D, of a circle is:
r =
so that,
C = 2
C = D
=
=
= 3.143
2. The distance around a circular region is known as it's circumference.
3. Given a circle of radius 35 cm, then:
A =
= x
= x 1225
= 22 x 175
A = 3850
Area of the circle is 3850 .
C = 2r
= 2 x x 35
= 2 x 22 x 5
= 220
C = 220 cm
Circumference of the circle is 220 cm.
