Question

Calculate the circumference and the area of a circle with radius 12,8 cm.​

Answer 1

Answer:

Step-by-step explanation:

Circumference of the circle = $2\cdot \pi\cdot radius$

                                              = 2(3.14)(12.8)

                                              = 80.384 cm

And the area of the circle = $\pi\cdot (radius)^2$

                                          = (3.14)(12.8)(12.8)

                                          = 514.4576 $cm^{2}$
