Answer:
50.29 in^2
Step-by-step explanation:
From the circumference we need to find the radius.
Since C = 2*pi*r, r = C / (2*pi).
Here, with C = 25 1/7 in, r = (25 1/7 in) / [ 2(22/7) ], or r = 4 in
The area of the cake is A = pi*r^2, or (here) A = (22/7)(4 in)^2 = 50.29 in^2
Answer:
2 CH4(g) + 4 O2(g) --> 2 CO2 (g)+ 4 H2O(g)
Step-by-step explanation:
The number are subscripts.
Now count the number of each kind of atom on the left and right side of the equation. Note, you have 4 H on the left and as written you have only 2 on the right. So add a coefficient-- a number in front of the formula.
CH4 +O2 ----- CO2 + 2 H2O
With the added coefficient in front of water, the number of hydrogens balance but the number of oxygens do not. There are only 2 oxygens on the left and a total of 4 oxygens on the right. A coefficient of 2 in front of oxygen on the left balances the equation.
1/2 x 5 equals 2.5
hope that helps lol
I don't know if this is right but i think the answer is 11 because as the number of people in the group goes up the price keeps decreasing by 3 so I made a table to see the difference...
1=42
8=39
9=36
10=33
11=30
The answer is A=81. You multiply 9 x 9 and then you get 81. Since all sides on a square are equal, you multiply the side length by itself to get the area. Hope that helps! Have a great day!
