Question

what is the circumference and diameter of a radius of 3.5 m​

Answer 1

Answer:

Diameter = 7m & Circumference = 22m

Step-by-step explanation:

Diameter = R X 2

= 3.5 X 2

= 7m

Circumference = 2 pie R

= 2 x 22/7 x 3.5

= 2 x 22 x 0.5 (because, 3.5 and 7 gets cancelled)

= 44 x 0.5

= 22m

Answer 2

Answer:

Diameter = 7m

Circumference of circle = 44m

Step-by-step explanation:

Given that radius = 3.5m

Diameter = 2 × radius = 2 × 3.5 = 7m

Circumference of a circle = 2πr

= 2 × 22/7 × 7

= 44 m
