Answer: 24 m
Step-by-step explanation:
Given: area of the circle is 144 π m² .
Area of a circle =
, where r= radius of the circle.
Then, ![144\pi = \pi r^2](https://tex.z-dn.net/?f=144%5Cpi%20%3D%20%5Cpi%20r%5E2)
Cancelling π from both sides , we get
![144 = r^2](https://tex.z-dn.net/?f=144%20%3D%20r%5E2)
Taking square root on both sides , we get'
![12= r](https://tex.z-dn.net/?f=12%3D%20r)
i.e. radius = 12 m
Then diameter = 2 (radius ) = 2 (12)= 24 m
Hence, the diameter of the circle is 24 m.
Answer:
width: 13 Length: 15
Step-by-step explanation:
Let length be x
width is x-2
perimeter is 56
P= 2(l+b)
56= 2(x +x-2)
56/2 = 2x - 2
28 + 2 =2x
30= 2x
15 =x
15-2+13
length =15
width = 13
The new width would be 4 inches, because to get from 12 inches to 2 inches you need to divide by 6, which means you must divide 24 by 6 as well, which equals 4. I hope this helps!
Step-by-step explanation:
5 hours I think bc if you add 2 1/2 with 2 1/2 you add 2 + 2=4 then 1/2+1/2=1 then add 1 and 4 and you get 5
