Alright Kofi — let's do this. Here's how to solve the problem: Given the area of a circle A = 154 cm^2. We will use = (22)/(7). Step 1: Find the radius (r). The formula for the area of a circle is A = r^2. 154 = (22)/(7) r^2 To find r^2, multiply both sides by (7)/(22): r^2 = 154 × (7)/(22) r^2 = 7 × 7 r^2 = 49 Take the square root of both sides to find r: r = sqrt(49) r = 7 cm Step 2: Find the diameter (d). The diameter is twice the radius: d = 2r. d = 2 × 7 cm d = 14 cm Step 3: Find the circumference (C). The formula for the circumference of a circle is C = 2 r or C = d. Using C = d: C = (22)/(7) × 14 cm C = 22 × 2 cm C = 44 cm Drop the next question.
