Question

if the angular measure of an arc is 36 and its length is 10 cm then what is the circumference of the circle? ​

Answer 1

Answer:

length of arc = 36/360 x 2π r = 10

1/10 x 2π r = 10

2 π r = 100 = circumference of the circle

thus the circumference of the circle is 100cm

Answer 2

Answer:

length of the arc=10cm

angle=36°

b. t. p

let the radius be r

we know

angle/360°X2πr=arc length

36°/360Xcircumference=10

1/10xcircumference=10

circumference=10x10

circumference=100

as 2πr=circumference

therefore circumference=100cm
