Answer:
1) 1.6 inch
2) 10.05inch
Step-by-step explanation:
radius = diameter/2 = 3.2/2 = 1.6 inch
circumference = 2πr = 2 * 3.14 * 1.6 =10.048=10.05inch
Answer:
r = 32
Step-by-step explanation:
R is the variable that we are trying to find.
24 = 3/4r
Since r is being multiplied by 3/4, we need to divide 3/4 on both sides to "undo" the multiplication.
24 / 3/4 = 3/4r / 3/4
32 = r
Therefore, r = 32.
To check, we can plug 32 into the equation.
24 = 3/4 x 32
3/4 x 32 = 24

Answer:
3
Step-by-step explanation:
Multiply both sides by x to get rid or the denominator: 
Get rid of the square root by squaring both sides:
= 4x + 15 = 9x
Just solve for x.
