Answer:
91+14π
Step-by-step explanation:
The question is incomplete. Find the complete question attached.
From the diagram shown;
It contains 4 quarter circles which is equal to a circle.
Perimeter of a circle = 2πr
r is the radius = length of one side of the square =7
Perimeter of the circle = 2πr
Perimeter of the circle = 2π(7)
Perimeter of the 4 quarter circles = 14π
Also in the diagram, there are 13 sides of the square present.
Perimeter of the squares = 13×length of one side of the square (Sum of all the sides)
Perimeter of the squares = 13×7 =91
Perimeter of the figure = Perimeter of the 4 quarter circles + Perimeter of the squares
Perimeter of the figure = 91+14π
The value of n in the given equation is -2.6
Step-by-step explanation:
Given,
10 =
To find the value of n
10 =
or, 10(3n+8) = 2 [ by cross multiplication]
or, 30n + 80 = 2
or, 30n = 2-80 [ taking the constant values in one side]
or, 30n = -78
or, n =
or, n = -2.6
