<u>Answer:</u>
When Anne pushes the wheelbarrow 25 meters the work done is 1120 joules
<u>Solution:</u>
We know 
Anne is pushing the wheelbarrow with a force of 70 N at an angle of
with the horizontal
So the force of Anne will be 
She pushes the wheelbarrow 25 meter, So D = 25 meters
So, the 
Anne has done total 1120 joules work.
Answer:

Step-by-step explanation:
1) c= 3.5cm × 22/7
c= 77cm/7 = 11cm
2) c= 2×3.14×5cm
= 6.28× 5cm
=31.4cm
3) L=180/360 × 22/7 × 3cm
= 1/2 × 22/7 ×3cm
=4.71 cm
4) c=12cm ×3.14
=37.68cm
5) c = 4.5cm × 3.14
=14.13cm
6) c = 6.7cm × 3.14
= 21.038cm
