3,5× 3 + 4 × 7 =3 8,5
46*4-42=143 46* 2- 4 2= 50
5,83+4*2=13,83 5,83+4*100=405,83
Answer:
10,087 cm³
Step-by-step explanation:
The volume of a pyramid is described by the formula
where B is the area of the base. In this case,
So
So then we substitute:
cm³
Answer:
Part 1: 5pi/6. Part 2: 10pi/3
Step-by-step explanation:
There are 60 minutes in an hour, and there are 360⁰ in a circle, so for every one minute that passes that is 6⁰ being passed.
From the time 25 to 50 is 25 minutes, which is also 150⁰.
To convert from degrees to radians you have to multiply 150⁰ by pi/180⁰ this turns into 5pi/6.
To find how far the tip of the clock moved you have to use arc length, which is arc length=radius×angle in radians.
we know that radius is 4, because thats the length of the minute hand times the degrees in radians which is 5pi/6.
4×5pi/6=20pi/6
this reduces to
10pi/3 which is how far the minute hand traveled.
Answer:
1050miles.
Step-by-step explanation:
since every 2 inches=350 miles, then 6 inches= 3(350miles)
since 6/2=3.
or you can think of it this way:
there are 3 2-inches in 6 inches, and every 2 inches, it's 350s miles.
350+350+350=1050miles.
