Step-by-step explanation:

4th one I dont know

Answer 2

Answer:

I knew only some answers and here are they

Step-by-step explanation:

2.154m²

Reason: Area of circle=πr²

22/7×7×7

Denominator 7 and one 7 gets cancelled

22×7=154m²

3.-101

Reason: -1×101 = -101

4.Infinite

Reason: A tennis ball is in the shape of a circle.Circle has infinite lines of symmetry

5.12

Reason: Everyone knows that a cuboid and cube has 6 faces,8 vertices (corners),12 faces

7.10

Reason: -5×2=-10

-10+10=0
