Steve is making a circular shield with a radius of 11 inches for a school play what approximate length of cardboard does he need to make the outer border of the shield
The circumference of a circle can be calculated using the formula C = 2πr, where r is the radius of the circle.
Given that the radius of the shield is 11 inches, we can calculate the circumference:
C = 2 x π x 11
C ≈ 2 x 3.14 x 11
C ≈ 69.08 inches
Therefore, Steve will need approximately 69 inches of cardboard to make the outer border of the shield.
