Question

Find the area A and circumference C of a circle of diameter 12 cm. Use 3.14 for . Round the result to the nearest tenth.

Answer 1

37.68 is C and 113.04 is the A

Answer 2

Answer:

Area: 113cm²

Circumference: 37.7cm

Step-by-step explanation:

to find area use the formula πr², π being Pi (3.14) and r being radius

radius = 6cm (half the diameter)

3.14 × 6² = 113.04cm²

to find the circumference use the formula πd

diameter = 12cm

3.14 × 12 = 37.68
