Answer:
She could divide 9.42 by Pi to find the radius, then multiply 9.42 by the radius.
(Last option)
Step-by-step explanation:
We need the formula for the area of a circle:
A = πr²
Remember r² = r × r
So you could rewrite the formula like this:
A = π × r × r
If π × r = 9.42, then the area becomes:
A = 9.42 × r
"Then multiply 9.42 by the radius".
To find "r", divide 9.42 by π.
π × r = 9.42
r = 9.42/π
"Divide 9.42 by Pi to find the radius".
