The surface area of a cube is simply the area of one face multiplied by 6, since all of the 6 faces are exactly the same, therefor:
Surface area = 5*5*6 = 150 ft^2
Answer:
10.2 m
Step-by-step explanation:
180 - 81 - 30 = 69
law of sines
x /sin 30 = 19/sin 69
x = 10.2
The diameter of the cylinder given = 3 yd.
the height given = 4 yd.
The radius is half of the diameter. So, the radius of the cylinder = (3/2)yd.
The formula to find the volume of the cylinder =
Where, r = radius, and h = height.
Now we can find the volume by plugging in the values of r and h in the formula.
The required volume of the cylinder
=
=
=
=
=
Volume of the cylinder = = 27.3 yd³
Given:
The equation is
To find:
The solution of the given equation.
Solution:
We have,
Subtracting both sides by 20, we get
Multiply both sides by 3.
Therefore, the solution of the given equation is .
Answer:
Step-by-step explanation:
a) 6 out of 10 are shaded. 6/10 = 60/100 so it is 60%
b) 11 out of 20 are shaded. 11/20 = 55/100 so it is 55%
