Question

The length of a side of a spuare is 7 cm and the diameter of a circle is 7 cm .which one has greater area? (Please solve it step by step)

Answer 1

Answer:

length of square has greater area

Step-by-step explanation:

Step1-

Sides of square=4multiply sides

7 cm =7multiply4=28

Area of square=Addition of all sides

Area of square is equal to Sides of square

Diameter of a circle=4 multiply 2=8

Answer 2

First, we need to find the area of the square and circle. Then we need to compare them.

Area of the square ⇒ Side²

Length of Side ⇒ 7cm

Area of the square ⇒ 7² = 49

∴The area of square is 49cm²

Area of the circle ⇒ $\frac{1}{4}\pi d^2$

Diameter ⇒ 7

Area of the circle ⇒ $\frac{1}{4}\pi 7^2$

⇒ $\frac{1}{4}\times \frac{22}{7}\times 49$

⇒ $\frac{11}{14}\times 49$

⇒ $\frac{77}{2}$

⇒ $38.5$

∴The area of the circle is 38.5cm²

Let's compare the areas of the square and the circle.

$49>38.5$

∴ The square has a greater area.
