Question

Find the radius and diameter of a circle that has
an area of 154 cm2. ( pi=3.14 )​

Answer 1

Answer:

The radius is 24.52cm and the diameter is 49.04cm...

Step-by-step explanation:

Circumference = 154cm

2πr = 154

2 x 3.14 x r = 154

6.28 x r = 154

r = 154÷6.28

r = 24.52

∴ The radius is 24.52cm...

We know that ,

Diameter = 2 x Radius

Diameter = 2 x 24.52

Diameter = 49.04cm..
