Question

maths class 7
Radius = ____
Diameter =_____
Circumference = 38 cm

find out the Radius and Diameter step - by - step​

Answer 1

Answer:

r= 133/22 cm and d=133/11 cm

Step-by-step explanation:

2πr=38 cm

38= 2×22/7×r

=38×7/44=r

=133/22 cm=r

so, d= 2r = 133/11 cm

Answer 2

Answer:

With the measure of the radius, you can tell a lot about the circle: its diameter (the distance from one side to the other, passing through the center), its circumference (how far around it is), and its area (how many square inches, feet, yards, meters — what have you — fit into it).
