Answer:
113.04 sq. in.
Step-by-step explanation:
If the diameter of the circle is 12", then the radius is 6" (half the diameter), and the area "A" is (approximately) 3.14 * 6^2. The calculation is approximate because 3.14 is a rounded value for pi.
Answer: 70.909090909091%
Step-by-step explanation: Reading through the problem we have <em>78 is</em>, that's 78 equals, <em>what percent</em>, x/100, <em>of 110</em>, times 110.
It's important to understand that <em>percent</em> means over 100 so what percent would simply mean <em>x/100</em> or any variable but I will be using x.
So we have the equation 
So cross canceling the 110 and 100 to 11 and 10, we have 
Multiply both sides by 10 to get rid
of the fraction and we have 780 = 11x.
Now divide both sides by 11 and 70.909090909091 = x.
So, 78 is 70.909090909091% of 110.

Answer:
The volume of this given solid figure is 18 cubic units.
Step-by-step explanation:
Here, given the volume of 1 small cube = 1 cubic units
Now, counting the total cubes in the given solid figure, we get
Number of cubes in base row = 10
Number of cubes in middle row = 6
Number of cubes in top most row = 2
So, the total number of cubes in the figure = 10 + 6 + 2 = 18 cubes
So, the volume of 18 cubes = 18 ( Volume of 1 small cube)
= 18 x (1 cubic units) = 18 cubic units
Hence, the volume of this given solid figure is 18 cubic units.
To solve this question, first cross multiply
Let ? = x
4/9 = x/81
4(81) = 9(x)
Simplify.
81 x 4 = 324
324 = 9x
Isolate the x, divide 9 from both sides
324/9 = 9x/9
x = 324/9
x = 36
4/9 = 36/81
36 is your answer
hope this helps!
