Question

If the diameter of the circle is 28cm. Find the radius and area of triangle​

Answer 1

Answer:

Radius = 12

Area = 452.39

Step-by-step explanation:

Answer 2

Given that :-

• the diameter of the circle is 28cm.

To find :-

• Find the radius and area of circle.

Formula used :-

• Radius = Diameter/2
• Area of circle = πr²

where,

• Diameter = 28 CM.
• π = 22/7.

Let us assume :-

• radius of circle is r.
• Area of circle is A.

Finding the radius of circle :-

According to the question,

⟾ r = D/2

⟾ r = 28/2 CM.

⟾ r = 14 CM.

Hence,

• The radius of circle is 14 CM.

Finding the Area of circle :-

⟾ A = πr²

⟾ A = 22/7×(14)²

⟾ A = 22/7×14×14

⟾ A = 3•14×14×14

⟾ A = 3•14×196

⟾ A = 615•44 cm².

Hence,

• The Area of circle is 615•44 cm².
