Question

diameter of circle is 28cm. taking pie equals to 22/7 find the area of circumference ​

Answer 1

Area of circle is 610 $cm^{2}$

Step-by-step explanation:

Step 1: Given, diameter=28 cm, π=$\frac{22}{7}$

we have to find area of circle

formula: area of circle= π$r^{2}$

r=$\frac{diameter}{2}$=14cm.

Step 2: area= $\frac{22(14)^{2} }{7}$

area=22×28

area=610 cm.

Answer 2

Answer:

GIVEN : DIAMETER = 28

SO, RADIUS = D/2 => 28/2 => 14

Circumference of a circle = 2πr

= 2 × 22/7×14

= 2 × 22 × 2

= 44 × 2

= 88

Step-by-step explanation:

DIAMETER is given,

FIRST : we will find RADIUS by dividing

DIAMETER by 2

SECOND : We will put the formula of the AREA

OF CIRCUMFERENCE and

THIRD : We will put the values

LAST : We will calculate and find the answer
