Volume is calculated by multiplying (3/4)pi by the radius cubed
The answer is: 12 centimeters.
The explanation is shown below:
1. By definition, all four sides of the square are equal and the diagonals are equal too.
2. Keeping the information above on mind, you know that AC and BD are equal:

3. Then, the length of BD is twice BE. So, you can calculate it as following:


4. Therefore, the lenght of AC is:

Answer:
The speed of car in miles per minute is
miles per minute and
The speed of car in mile per hour is 40 miles per hour,
Step-by-step explanation:
Given as :
The distance cover by car = 2
=
miles
The Time taken by car to cover distance = 3
min =
min
The speed o car in miles per minute = S miles/min
So, Speed = 
Or, S =
mie per min
∴ S =
miles per minute
Now, Let The speed of car in miles per hour = x miles/h
So, Time in hour =
×
=
hours
So , Speed = 
Or, x =
miles per hours
Or, x = 40 miles per hours
Hence The speed of car in miles per minute is
miles per minute and the speed of car in mile per hour is 40 miles per hour, answer
Answer:
x = 88.2
Step-by-step explanation:
The angle at the top of the triangle = 90° - 10° = 80°
and the left side of the triangle is x ( opposite sides of a rectangle )
Using the tangent ratio in the right triangle
tan80° =
= 
Multiply both sides by x
x × tan80° = 500 ( divide both sides by tan80° )
x =
≈ 88.2
It's Feedback A. B is wrong because natural numbers would be reversed with whole numbers, and c is wrong because irrational numbers would be outside.
