Question

A circular pizza has a diameter of 12 inches and is cut into 10 congruent slices. What is the area of each slice, to the nearest tenth?
Group of answer choices

14.4 straight pi inches squared

3.6 straight pi inches squared

2.4 straight pi inches squared

12.4 straight pi inches squared

Answer 1

• Diameter=12in
• radius=r=12/2=6in

$\\ \sf\longmapsto Area=2\pi r$

$\\ \sf\longmapsto Area=2(3.14)\times 6$

$\\ \sf\longmapsto Area=2(18.84)$

$\\ \sf\longmapsto Area=37.68in^2$

Now area of each slice

$\\ \sf\longmapsto \dfrac{37.68}{12}$

$\\ \sf\longmapsto 3.6in^2$
