Question

find the area of a circle whose diameter is 1.4 m

Answer 1

Answer:

1.54m^2

Step-by-step explanation:

area of circle = πr^2

                     diameter= 1.4 m

                      radius=d/2=1.4/2

                                        =0.7 m

                              area of circle= (22/7) *0.7 *0.7

                                                     =22*0.1*0.7

                                                     =1.54 m^2

Answer 2

Hey mate


Here's your answer


D = 1.4
r = d/2 = 1.4/2 = 0.7 m

Area of Circle
= πr²
= 22/7 X 0.7 X 0.7
= 22/7 X 0.49
= 1.54 m²
