Question

A cake has a circumference of 25 1/7 inches. What is the area of the cake? Use 22/7 to approximate pi. Round to the nearest hundredth.

Answer 1

Answer:

Step-by-step explanation:

$Circumference=25\frac{1}{7}\\\\\i \pi*d=\frac{176}{7}\\\\\frac{22}{7}*d=\frac{176}{7}\\\\d=\frac{176*7}{7*22}\\\\d=8$

r = 8/2 = 4 inches

Area=πr²

$=\frac{22}{7}*8*8\\\\=\frac{1408}{7}\\\\=201.14 inches^{2}$
