The answer would be 153.86... First of all let's establish the formula to work out the area if a circle - it's area = pi * (radius * radius)... Then let's substitute the values... So we know that the diameter is 14 inches so that must mean the radius is 7 inches, since the radius is simply half of the diameter... Then we multiply pi (I am using 3.14) with 49 inches (since 7 * 7 = 49)... Then the answer you get is 153.86

Answer:
P=12.8 in A=33
Step-by-step explanation:
Well those triangles are congruent and we can solve it by proportion, so we have :
We can solve them by proportions because they are congruent. So, we can do it .
X-perimeter of triangle with side 3.2.
Here we make proportions :
3.2:x=5.8:23.2
3.2*23.2=5.8*x
x=12.8
Now, let find area
3.2:Y=5.8:59.8
3.2*59.8=5.8*x
Y=32.99=33
Answer:
(D)
Step-by-step explanation:
The given expression is:
Upon simplifying the above expression, we get
=
=
Solving the like terms together, we have
=
which is the required simplified form of the given expression.
Hence, option D is correct.
Answer:
Irrational, because it is non-terminating and non-repeating So Its Irrational.
