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
