Answer:

The area of the shaded region is 125.664 square centimetre

Step-by-step explanation:

Area of the shaded region = area of the circle with radius 7 cm - area of the circle with radius 3 cm----- --(1)

Step 1: Finding the area of the circle with radius 7 cm

Area of the circle A = πr²

On substituting the value of the radius,

we get

Area of the circle A =T (7)²

Area of the circle A centimetre-------- 49 square -(2)

Step 2: Finding the area of the circle with radius 3 cm

Area of the circle a = πη2

On substituting the value of the radius,

we get

Area of the circle a = π(3)²

Area of the circle a = 9 square

centimetre ---➖➖➖➖➖➖- -(3)

Step 3: Finding the area of the shaded

region

Area of the shaded region =49π - 9π

= 40π

= 125.664 square centimetre

Answer:

it will be 41.27

Step-by-step explanation:

area of circle = pi(r)^2

= pi*4^2 =16pi

then find the area of the square = lw= 3*3 = 9

now subtract == 16 pi - 9 = 41.27

ur welcom
