Answer:
area=38.465, circumference=21.98
Step-by-step explanation:
Divide the diameter by 2 to find the radius
7/2=3.5
Use the formula πr^2 find area
3.5*3.5=12.25
12.25*3.14=38.465
a=38.465
Then, use the formula 2πr to find circumference
2*3.14=6.28
6.28*3.5=21.98
c=21.98
Answer:
The slope of this curve where it meets the right pole is 1.130
The angle between the line and the right pole is 41.51
°
Step-by-step explanation:
Given that ;



x = 9 m;( i.e half of the distance of the two poles at 18 meters apart.

= 1.130
The slope of this curve where it meets the right pole is 1.130
The angle between the line an the right rope can be determined by using the tangent of the slope .
tan ∝ = 1.130
∝ = tan⁻¹ (1.130)
∝ = 48.49°
The angle is θ; so
θ = 90 - ∝
θ = 90 - 48.49°
θ = 41.51
°
Thus; the angle between the line and the right pole is 41.51
°
For this case we must simplify the following expression and find the value of the variable "x":

We apply distributive property to the terms of parentheses:

We add similar terms:

We subtract 4x on both sides:

We add 11 to both sides:

Answer:

Answer:
- 22.76
Step-by-step explanation:
if b = - 0.16 the you subtract that with - 22.6
- 0.16 - 22.6 = - 22.76
