Question

Calculate the area of the designed region in the given figure, common
between two quadrants of circles of radius 7 cm each.​

Answer 1

Answer:

area of two adjacent quadrants i . e. hemisphere = 77 cm square

Step-by-step explanation:

given,

the radius of a circle = 7 cm

adding the two adjacent quadrant will become a hemisphere

so, here we need to find area of hemisphere

=

$\pi{r}^{2} \div 2$

= (22/7 ×7×7 ) / 2

= (22×7) /2

= 154/2

= 77 cm square
