Question

the circumference of a circle is 220 find its radius and its area pi is equal to 3.14​

Answer 1

Answer:

radius = 35.031

Step-by-step explanation:

2 Pie r = 220

2×3.14×r = 220

r = 220/ 2×3.14

r= 35.031

Answer 2

Step-by-step explanation:

$circumference \: = 2\pi \: r \\ 220 = 2 \times 3.14 \times r \\ \frac{220}{2 \times 3.14} = r \\ \frac{110}{3.14} = r \\ 35.03 = r \\ radius = 35.03cm \\ \\ area = \pi \: {r}^{2} \\ = 3.14 \times 35.03 \times 35.03 \\ = 3853.09 {cm}^{2}$
