Answer:
C = 10π ft
Step-by-step explanation:
the circumference (C) of a circle is calculated as
C = 2πr ( r is the radius )
to find r use the area formula, that is
A = πr² = 25π ( divide both sides by π )
r² = 25 ( take square root of both sides )
r = = 5
then
C = 2π × 5 = 10π ft
Y = 7^3 + 1 is a constant value, all of the others include an x variable in the form of a linear function.
Answer:
3
Step-by-step explanation:
Start by listing all the numbers 48 and 81 are divisible by
48: 1,2,3,4,6,8,12,16,24,48
81: 1,3,9,27,81
Now that we have all those listed look between the two and find the largest number that shows up on both lists, in this case it is 3
I hope this helps and please don't hesitate to ask if there is anything still unclear!
94
(85+89+92+x)/4 = 90
(266+x)/4 = 90
(Multiply by 4 on each side to get rid of it)
266+x=360
(subtract 266 from each side)
x = 94
If u like use subtract and addition to it it would be 1089
