Answer 1

Steps: 2 Marks
Answer: 1 Mark

Given that:
The boy starts putting sauce on the pizza and turns his hand around the pizza for six and half times.
We know that in one revolution there are 4 right angles.
$\therefore$ In 6 revolutions, the number of right angles= 6$\times$4=24
$\therefore$ In half revolution, the number of right angles = $\frac{1}{2}$$\times 4$=2
The total number of right angles = 24 + 2 = 26.
The boy turned through 26 right angles.
