Answer:
x = 2 + 5i√2 / 6 and x = 2 - 5i√2 / 6
Step-by-step explanation:
If this isn't right, I'm sorry. Also, you can put x = 2 ± 5i√2 /6 to make it shorter and not have two answers. Hope this helps :)
Circumference of a circle having radius of 27 yard can be found using the formula, π = 2(Area of Circle)/r, which is C = 169.6 yd
<h3>What is the Circumference of a Circle?</h3>
- Circumference of a circle is the distance round the circle.
- Circumference = Perimeter
- Circumference of a circle without using π = 2(Area of Circle)/r.
Given:
radius of circle = 27 yd
Thus:
Area = πr² = π(27)²
Area = 2,290.2 yd²
Circumference of a circle without using π = 2(2,290.2)/27
= 169.6 yd.

Step-by-step explanation:
4,500÷90=50
and to check
90×50=4500
Answer:
Height of the cylinder = 1.60yd
Step-by-step explanation:
Volume of a cylinder =
V = πr^2h
V - volume of cylinder
π - 3.142
r - radius of cylinder
h - height of cylinder
We are provided with
V - 80
r - 4
π - 3.142
h - ?
80 = 3.142 * 4^2 * h
80 = 50.272 * h
To find h, divide both sides by 50.272
80/50.272 = 50.272h/ 50.272
1.599 = h
h = 1.60yd
