Answer:
The circumference is 45.2yd
Step-by-step explanation:
Given
--- diameter
Required
Determine the circumference
The circumference is calculated as:

So, we have:

Take pi a 3.14


Approximate

Answer:
Length= 130 cm
For, Width= 91 cm
Step-by-step explanation:
Ratio of the width to the length of the rectangle = 7:10
Width of the rectangle= 91 cm

As, Width = 91 cm

On, Cross multiplication the fraction:


Dividing by '7' both the sides:

Answer:
This question seems to be incomplete, I guess that we have a circular pool, with a diameter of 3.5 m.
Now, the circunference of a circle can be written as:
C = 2*pi*r
where:
pi = 3.14
r = radius = half of the diameter = 3.5m/2 = 1.75m
Then replacing those values in the equation for the circumference we have:
C = 2*3.14*1.75m = 10.99 m.
And knowing that the value of pi is actually larger than 3.14 (pi = 3.1415926535....)
We can safely round up the circumference to the next whole number, C = 11m
K= 10(-7) -19
k= -70-19
k=-89
Answer:
zeros: -11 , 7
Line of symmetry: x = -2
Step-by-step explanation:
y = 2x² + 8x - 154 = 2*(x² + 4x - 77) = 2*(x+11)(x-7)
y = 0
x = - 11 or x = 7
line of symmetry: x = 1/2 (-11 + 7) = -2
2x² + 8x - 154 = 2*(x² + 4x +4) - 162 = 2 * (x+2)² - 162
vertex (h , k): h = -2 , k = -162
Line of symmetry: x = -2
