Alright, lets get started.
We have given a circle which has 56 cm radius.
We are asked to find its circumference.
The formula for circumference of circle = 2 pi r
Putting the value of pi and r
So the circumference = 2 * 2.142 * 56
Simplifing
Hence the circumference of circle = 351.9 cms
Answer is 351.9 cm
Hope it will help :)
Answer:
1). x = 81
2). x = 84
Step-by-step explanation:
1). By applying geometric mean theorem in the given triangle,

56x = (18√14)²
56x = 4536
x = 
x = 81
2). By applying geometric mean theorem,

16x = (8√21)²
16x = 1344
x = 
x = 84
Answer: 31
Step-by-step explanation:
To find the distance, find the difference between the number.
23 - (-8) = 31 So the distance is 31 units.
Note: To go from -8 to 23 you will have to add 31 to -8 and to go from 23 to -8 you will have to subtract 31 so the distance is 31
Like terms: in the case of exponents, the same exponents for different numbers
Like 7x and 8x are like terms.
5x and 6x^2 would be unlike terms
Get it??
Good luck~~
