A cake has circumference of 2517 25 1 7 inches. What is the area of the cake? Use 227 22 7 for π π . Round to the nearest hundre

S_A_V [24]

Answer:

22in²

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Circumference = 25 (1/7)

As we know,

Circumference of a circle = 2πr

By solving this we get

Radius (r) = 4in

Now. we can calculate the area by using following formula,

Area = πr²

By putting the value, we get

Area = (22/7) × 4²

= 22/7 × 16

= 352÷16

Area = 22in²
