Question

Ms. Long ordered a pizza with a radius of 4 ft. What is the area of the pizza Ms. Long

ordered? Round to the nearest hundredth.

Answer 1

Ms. Long ordered a pizza with area 50.24 ft².

Step-by-step explanation:

Solution :

Here, we have given that the radius of circular pizza is 4 ft.

So, finding the area of circular pizza by substituting the values in the formula :

`\longrightarrow{\pmb{\sf{Area_((Circle)) = \pi{r}^(2)}}}`

`\longrightarrow{\sf{Area_((Pizza)) = 3.14{(4)}^(2)}}`

`\longrightarrow{\sf{Area_((Pizza)) = (314)/(100) * {(4 * 4)}}}`

`\longrightarrow{\sf{Area_((Pizza)) = (314)/(100) * (16)}}`

`\longrightarrow{\sf{Area_((Pizza)) = (314)/(100) * 16}}`

`\longrightarrow{\sf{Area_((Pizza)) = (314 * 16)/(100)}}`

`\longrightarrow{\sf{Area_((Pizza)) = (5024)/(100)}}`

`\longrightarrow{\sf{Area_((Pizza)) = 50.24 }}`

`\star{\underline{\boxed{\sf{\purple{Area_((Pizza)) = 50.24 \: {ft}^(2)}}}}}`

Hence, the area of pizza is 50.24 ft².

`\rule{300}{2.5}`

Answer 2

50.24 ft²

Explanation:

We know that

Area of circle = πr²

=> 3.14 × (4)²

=> 3.14 × 16

=> 50.24 ft²

Hence,

area of pizza is 50.24 ft²
