What is a decimal number?

The decimal number is such that it contain a whole part as well as a fraction part, a whole part before the point and a fractional part after the point.

Given that, 5 over 9.

Mathematically, we can write it as, 5/9 or 5÷9

5/9 = 0.55555.....

Hence, The correct answer will be 0.555...

154 sq. cm is the area of a circle
so find its radius
\pi =(22)/(7)

Answers

Answer:

r = 7 cm

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( where r is the radius )

Given A = 154 , then

πr² = 154 , that is

(22)/(7) r² = 154 ( multiply both sides by 7 to clear the fraction )

22r² = 1078 ( divide both sides by 22 )

r² = 49 ( take square root of both sides )

r = √(49) = 7 cm
