Answer:
5.73cm
Step-by-step explanation:
Given parameters:
Circumference of the circle = 36cm
Unknown
Length of the radius = ?
Lets represent the radius by r
Solution
The circumference of a circle is the defined as the perimeter of a circle. The formula is given as:
Circumference of a circle = 2πr
Since the unknown is r, we make it the subject of the formula:
r = 
r = 
= 
= 5.73cm
Answer:
2 Paul's Survey sample only included tenth graders

Answer:
10x^2 - 4x
Step-by-step explanation:
5x - 2 times 2x will equal the area of 'Potatoes.'
5x times 2x is 10x^2.
2 times 2x is 4x.
I cannot provide an exact value because x hasn't been identified.
I hope this helps.
Answer:
x = 13
Step-by-step explanation:
y=50
50 = 5x - 15
50 + 15 = 5x
65 = 5x
65/5 = 5x/5
13 = x
The two integers are 3 and 9.
3^2+9^2=90
9*3=27
9+3=12
The sum of the two integers is 12.
