Answer:
The area is 12.56, and the circumference is 12.56.
Step-by-step explanation:
For the area,
We need to use the formula A=3.14*radius*radius
So we plug it in, and we get 3.14*2*2, which is 12.56 centimeters squared.
For circumference, we need to do,
C = 3.14*diameter
To find the diameter we need to do 2 (radius) x 2 which is 4
Plugging it in that would be 3.14 * 4 which is 12.56
So, in this case, the area is 12.56, and the circumference is also 12.56.
I think it is 84.8528137424cm^2
Imagine to have three segment: 1 is x, another is x+7 and the last is x-5. You know that their sum is 50, so you can write:
x+(x+7)+(x-5)=50
simplify:
3x+7-5=50
3x=48
x=16
16+7=23
16-5=11
So the thee sides are 11, 16 and 23.
Hope this helped.
Step-by-step explanation:
its say $3.50 each so for a week you multiply $3.50 by 3 because the are 3 days which will be equal to $10.5
the you divide $84 by $10.5
and the answer is =8weeks
