The area of the first, second, third, and fourth circles will be 56.72 cm², 36.3 ft², 167.33 m², and 188.6 yd² respectively.
What is a circle?
It is the centre of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.
Then the radius and diameter are given below.
[tex]\rm r_1 = 4 \dfrac{1}{4} = \dfrac{17}{4} = 4.25 \ cm\\\\\\r_2 = \dfrac{d}{2} = \dfrac{6\frac{4}{5}}{2} = \dfrac{34}{10} = 3.4 \ ft\\\\\\r_3 = \dfrac{d}{2} = \dfrac{14.6}{2} = 7.3 \ m\\\\\\r_4 = 7\dfrac{3}{4} = \dfrac{31}{4} = 7.75 \ yd[/tex]
Then the area of the circle is given as
Area = π × r²
Then the area of the first circle will be
Area = π × r₁²
Area = 3.14 × 4.25²
Area = 56.72 square cm
Then the area of the second circle will be
Area = π × r₂²
Area = 3.14 × 3.4²
Area = 36.3 square ft
Then the area of the third circle will be
Area = π × r₃²
Area = 3.14 × 7.3²
Area = 167.33 square m
Then the area of the fourth circle will be
Area = π × r₁²
Area = 3.14 × 7.75²
Area = 188.6 square yd
