Answer 2

Answer:

32 = 2(3.14) * r

Multiply 2 * 3.14

32 = 6.28r

Solving

32 = 6.28r

Solving for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Add '-6.28r' to each side of the equation.

32 + -6.28r = 6.28r + -6.28r

Combine like terms: 6.28r + -6.28r = 0.00

32 + -6.28r = 0.00

Add '-32' to each side of the equation.

32 + -32 + -6.28r = 0.00 + -32

Combine like terms: 32 + -32 = 0

0 + -6.28r = 0.00 + -32

-6.28r = 0.00 + -32

Combine like terms: 0.00 + -32 = -32

-6.28r = -32

Divide each side by '-6.28'.

r = 5.095541401

Simplifying

r = 5.095541401
