Question

Find the circumference of a circle whose
area is 946 cm.^2​

Answer 1

Answer:

The circumstance of the circle = 108 cm

Step-by-step explanation:

Given that,

the area of the circle = 946 cm²

area of circle = πr²

where,

r us radius of the circle

so,

πr² = 946

r² = 946/π

r² = 946 × 7/22

r² = 43 × 7

r² = 301

r = √301

r = 17.35 cm

now,

Circumference of the circle = 2πr

putting the values,

= 2 × 22/7 × 17.35

= 108 cm

so,

The circumstance of the circle = 108 cm

Answer 2

Answer :

108.68 cm

Explanation :

area = 946 cm^2

area - πr^2

946 = 22/7 *r^2

946*7/22 = r^2

301 = r^2

√301 = r

17.35 cm =r

circumference -2πr

= 2*22/7*17.35

= 44*2.47

= 108.68 cm

hope its correct and helps u!!
