Answer: 44%
Step-by-step explanation:
For a circle of radius R, the area is written as:
A = pi*R^2
Where pi = 3.14
If we increase the radius by 20%, the new radius will be:
R´ = R + 0.20*R = 1.20*R
The new area will be:
A´ = pi*(1.20*R)^2 = (1.20)^2*pi*R^2
= 1.44*pi*R^2
And pi*R^2 = A, the original area, then_
A´ = 1.44*A = A + 0.44*A
This means that the percentage in which the area increased is:
0.44*100% = 44%
A equals 54
im thinking b equals 12 but i could be wrong
a is right though
I'm not sure if this is correct but I think it might be 148.82
this is how I got my answer
1,908×7.8%=148.824 (put in the correct format it is 148.82)
148.82×12×14= 25,001.76
Your answer will be C, 11.3. 42 numbers all together, add them up and you get 476 then you divide it by 42 and get 11.3
