The area of a 154cm square calculate radius

Answer 1

There are different shapes that could have an area of 154cm squared, so we need more information to determine the radius.

If the shape is a circle, we can use the formula for area of a circle:

A = πr^2 where A is the area and r is the radius.

We can solve for the radius:

r = √(A/π) = √(154/π) ≈ 7.85 cm

If the shape is a square, we can use the formula for area of a square:

A = s^2 where A is the area and s is the length of a side.

We can solve for the length of a side:

s = √A = √154 ≈ 12.41 cm

Again, we cannot determine the radius with this information because a square does not have a radius.
