Answer:
50.24 in
Step-by-step explanation:
to find how far it it will go you will need to find the circumference and times it by 2 to find the circumference the formula is 2*pi*radius so you would do 2*3.14*4 and that is 25.12 but since it is 2 revolutions you times 25.12 by 2
100s place. So 3 by 100s is 300.
Answer:
volume of a cylinder = 401.92cm³
Step-by-step explanation:
to calculate the volume of a cylinder , we will use the formular for finding the volume of a cylinder
volume of a cylinder = πr²h
given that
height of the cylinder = 8cm
radius of the cylinder = 4cm
volume of a cylinder = π × (4cm)² × 8cm
volume of a cylinder = π × 16cm² × 8cm
volume of a cylinder = π128cm³
value of π = 3.14
volume of a cylinder = 3.14 × 128cm³
volume of a cylinder = 401.92cm³
Since it is an equilateral triangle, all sides are the same, so all amplitudes are the same.
You should use the pythagorean theorem to find the altitude.
How?:
1) Split the triangle in half. You will now have a right triangle with side C=46 and either A or B= 23.
2)Now plug these values into the equation(I chose to plug 23 in as A)
a^2 +b^2=c^2.
3) This gives you:
23^2+b^2=46^2
4) Isolate the variable and solve:
23^2+b^2=46^2
b^2=46^2-23^2
b^2=1587
5) The square root of 1587 is 39.8
The answer is 39.8 cm:)
I hope you learned something!
(^2 means squared, the ^ means the following number is the exponent, just in case ya didn't know)
Area is Length x Width, so dividing the area (48) by the length (6) will get you a width of 8 meters
