Find the area and circumference of circle with the radius. ​

Answer 1

Answer:

Area= 2464 cm²

Circumference= 176 cm

Step-by-step explanation:

Area of circle = πr² = 22/7 × 28 ×28

= 2464 cm²

Circumference of circle = 2πr = 2× 22/7×28

= 176 cm

Answer 2

Answer:

$circumference \: of \: circle = 2\pi \: r$

$= 2 \times \frac{22}{7} \times 28 \: {cm}$

$= 2 \times 22 \times 4 \: cm$

$= 176 \: cm$

$area \: of \: circle \: = \pi \: {r}^{2}$

$= \frac{22}{7} \times 28 \times 28 \: {cm}^{2}$

$= 22 \times 4 \times 28 \: {cm}^{2}$

$= 2464 \: {cm}^{2}$

hope it helps
