Q) 7) d &f( option 2)

Step-by-step explanation:

In the first question,you find area of bigger and smaller circle. Then subtract area of smaller circle from area of bigger circle.You get the answer.

Hope it helped

Answer 2

Answer:

6. (1) 19096 sq. mm

7. (2) angle d and angle f

Step-by-step explanation:

6. Area of outer circle= πr²

= 22/7×224×224

= 157696 mm²

Area of inner circle= πr²

= 22/7×210×210

= 138600 mm²

Area of thr ring = (157696-138600) mm²

= 19096 mm2
