Question

I need help pls just this one math question

Answer 1

Answer:

7.625

Step-by-step explanation:

bcoz area of circle using r=5/2

area=19.625

area of rectangle=12

area of shaded area =7.625

Answer 2

Qúestión :-

Calculate the area of the shaded region in the figure. Use 3.14 for π and round to nearest tenth, if necessary.

Solútion :-

Area of shaded region

= Area of circle - Area of rectangle

~ Area of Circle = πr^2

• π = 3.14
• r = 5/2 = 2.5

Area = 3.14 x 2.5 x 2.5

= 19.6cm^2

~ Area of rectangle = L x B

• L = 4cm
• B = 3cm

Area = 4 x 3

= 12cm^2

~~ Area of Shaded region = 19.6 - 12

= 7.6cm^2
