Question

find the circumference and area of each circle of diameter is equal to 1.4m​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

Circumference = 4.4cm.

Area = 1.54 cm.

Step-by-step explanation:

Given,

Diameter = 1.4 m

Circumference = 2πr

                         = 2r × π

                         = 1.4 x 22/7

                         = 4.4 cm

Radius of circle = d/2

                          = 1.4/2

                          = 0.7

Area of circle = πr ²  ( π = 22/7 )

                      = 22/7 (0.7)²

                      = 22/7 x 0.7 x 0.7

                      = 1.54  cm.
