What is the area of a circle with a radius of 7 centimeters ? (Use 3 point 1 4 for pi and round to the nearest tenth.)

Use the circle area formula, A = πr². With a radius of 7 centimeters and π = 3.14, the area is 3.14 × 7² = 3.14 × 49 = 153.86 square centimeters. Rounded to the nearest tenth, this is 153.9 square centimeters, so the correct choice is 153.9 cm².
