Step-by-step explanation:
π= 3.14
Given
Circumference = 12.56 units
First calculating radius
so 2πr = 12.56
2 * 3.14 * r = 12.56
6.28 r = 12.56
Therefore r = 2 units
Now calculating Area
Area = πr²
= 3.14 * 2²
= 12.56 square units
C I think because if you multiply 5 to everything you would get c
Answer:
Father's age = 48
Daughter's age = 24
Step-by-step explanation:
Let x be father's age and y be daughter's age.
1st equation:
x = 2y
2nd equation:
(x - 16) = 4(y - 16)
Replacing value of x from 1st equation,
(2y - 16) = 4(y - 16)
2y - 16 = 4y - 64
4y - 2y = 64 - 16
2y = 48
y = 48/2
y = 24
And,
x = 2y
x = 2 x 24
x = 48
8x - x = 64 - 16
7x = 48
Answer:
9y-24
Step-by-step explanation:
3(y-8)+3(2y)
3y-24+6y
9y-24
An integer is a whole number.
The answer isn't A, because 6/3=2 and 2 is a whole number.
The answer isn't C, because 6/2=3, and 3 is a whole number.
The answer therefore has to be B, because 3/6=1/2 and 1/2 isn't a whole number or an integer.
