Question

13. A table top is semi circular in shape with diameter 2.4 m. Find the area of the
table top. (Take π =3.14)
​

Answer 1

Answer :-

Given :-

• Diameter of semicircle = 2.4 m

To Find :-

• Area of table top

Solution :-

Here, we are given diameter. So, we first need to find the value of radius. Then we need to substitute the value in the formula used for semi-circle.

Area of semi-circle = πr² / 2

→ Radius = Diameter / 2

→ r = 2.4 / 2

→ r = 1.2

• π = 3.14
• r = 1.2 m

Substituting the values -

→ Area = 3.14 × (1.2)² / 2

→ Area = 3.14 × 1.2 × 1.2 / 2

→ Area = 1.57 × 1.2 × 1.2

→ Area = 2.2608

Area of table top = 2.2608 m²

Answer 2

QuestioN :

A table top is semi circular in shape with diameter 2.4 m. Find the area of the  table top. (Take π =3.14)

GiveN :

• Diameter of semicircle = 2.4 m
• π =3.14

To FiNd :

• The area of the  table top.

ANswer :

The area of the  table top = 2.2608 m²

SolutioN :

$\sf Formula \:to\:be\:used :-$

Area of semi-circle = πr² / 2

$\sf \rightarrow Radius = \frac{Diameter}{2}$

$\rightarrow \sf r = \frac{2.4}{2}$

$\rightarrow \sf r = 1.2$

$\sf Substituting \:the\: values :-$

$\sf \rightarrow Area = 3.14 \:x\: (1.2)^2 / 2$

$\rightarrow \sf Area = 3.14 \:x\: 1.2 \:x\: 1.2 / 2$

$\rightarrow \sf Area = 1.57 \:x\: 1.2 \:x\: 1.2$

$\rightarrow \sf Area = 2.2608$

∴Hence, The area of the  table top = 2.2608 m²
