Question

The area of a sector of a circle whose radius and length of the arc are 10 cm, 13 cm respectively is

Answer 1

Area of sector = 1/2 lr
= 1/2 × 13 × 10
= 13 × 5
= 65 cm^2

Answer 2

Aɴsᴡᴇʀ:

• The area of the sector of a circle = 65 cm²

Gɪᴠᴇɴ:

• The radius of the sector = 10 cm.
• The length of the arc = 13 cm.

Nᴇᴇᴅ Tᴏ Fɪɴᴅ:

• The area of the sector of a circle = ?

Solution:

Fᴏʀᴍᴜʟᴀ ᴜsᴇᴅ ʜᴇʀᴇ:

• Area of sector = (Length × Radius)/2

Pᴜᴛᴛɪɴɢ ᴛʜᴇ ᴠᴀʟᴜᴇs

➦ Area of sector = (13 × 10)/2

➦ Area of sector = 130/2

➦ Area of sector = 65 cm²

Tʜᴇʀᴇғᴏʀᴇ:

• The area of the sector of a circle is 65 cm².
