Question

diameter = 10. find circumference of circle.​

Answer 1

Answer:

C≈31.42

Step-by-step explanation:

C=2πr

d=2r

Solving forC

C=πd=π·10≈31.41593

Answer 2

•Given-

• Diameter = 10 cm

•To find-

• Circumference of the circle

~We know that

➥ C = 2πr

~where,

➨C = circumference

➨π = 22/7 = 3.14159

➨r = radius

•Diameter to radius

➽ r = d/2

➽ r = 10/2

➽ r = 5

•Solution-

➾ C = 2πr

➾ C = 2×3.14159×5

➾ C = 6.28318×5

➾ C = 31.41590
