Answer:
25.85
Step-by-step explanation:
The area of a circle is given by A = π * r²
We have the value of the area, so we clear r:
r² = A / π
r² = 2100 / π = 668.45
r = √668.45 = 25.85
Answer:
Solve for z by simplifying both sides of the equation, then isolating the variable.
Exact Form:
z = 63/2
Decimal Form:
z = 31.5
Mixed Number Form:
x = 31 1/2
