Answer:
Half of 2 is 1(new radius)
1^1 = 1
1 x 3.14 = 3.14
Now we multiply the area of the circle by the height to get the volume.
3.14 x 3 = 9.42
He said he would pay 3.18 per every square foot so now we multiply 3.18 by 9.42.
9.42 x 3.18 = 29.9556 rounded = it is around $30.
Answer:
Step-by-step explanation:
Answer:
a=3.33m/s^2
Step-by-step explanation:
F=ma
a=F/m
To find Force you have to subtract the gravitational force by the air force
F=600-400
F=200N
m=60kg
Plug in the values:
a=200N/60kg
a=3.33m/s^2
Answer:
50 ft.
Step-by-step explanation:
It is given that the ratio of width-to-length is 2 : 5.
Let,
Width = 2x ft
Length = 5x ft
Perimeter of the rectangle is
It is given that the perimeter of the rectangle is 140 ft.
Divide both sides by 14.
The value of x is 10.
Therefore, the length of the rectangle is 50 ft.
I think I got it. Correct me if I am wrong.
Parallelogram diagram I believe down below. We must find the height and then the area using Pythagorean theorem. Since the green shaded part is a 30-60-90 triangle, the base is 1/2 the hypotenuse, therefore it is 3. Now we calculate the height with it.
A^2 + B^2 = C^2
A^2 + 3^2 = 6^2
A^2 + 9 = 36
A^2 = 27
A = 3√3
Therefore the height is 3√3
Now calculate the area using A = bh
A = bh
= (12)(3√3)
= 36√3
So the area is 36√3 square units.
I cannot be sure of this answer because you did not provide a diagram.
