Answer:
Radius = r = 7.5
Diameter = d = 15
Circumference = C = 15π
Step-by-step explanation:
We are given the image of a circle with a straight line passing through the center of the circle and touching its edges. Such a line is known as the diameter of the circle. From the image we can see the length of the diameter of the circle is d = 15 units.
Radius is define as half of the diameter. Since the diameter is 15 units, the radius of the given circle will be half of 15 which is r = 7.5 units.
Circumference of the circle = C = 2πr
Using the value of radius(r), we can write the circumference as:
C = 2π(7.5) = 15π
There are 360 degrees in a circle
10x+5+140+45+2+11x=360
21x+192=360
21=168
X=8
Eb would be the same as the central angle
80+5=85
Answer:
C ) 10/m⁵
Step-by-step explanation:
In this question, we have to find the product of two terms
First term = 5 m⁻²
Second term = 2 m⁻³
Product of both terms = (5 m⁻²) · (2 m⁻³)
The simple way of calculating product of these two term which involves constants as well as variable is that we multiply the constants together:
5·2 = 10
And we multiply the variables. According to the rules of multiplication, when 2 same constants or variables are multiplied, we can just add their powers to get the result.
(m⁻²) · (m⁻³) = m⁻²⁻³ = m⁻⁵
The product of both terms can be written as:
(product of constants)(product of variables) = (10)(m⁻⁵) = 10/m⁵
So the correct option is C
