Question

the perimeter of a sector of a circle of radius 4cm and formed by an arc of measure 11cm​

Answer 1

Answer:

• 19cm is the required perimeter of given sector.

Step-by-step explanation:

According to the Question

It is given that,

• Length of Arc = 11cm
• Radius ,r = 4cm

we have to calculate the perimeter of a sector of a circle.

As we know Perimeter of a sector of a circle is calculated by

Perimeter of a sector = Length of Arc + 2Radius

substituting the value we get

↠ Perimeter of a sector = 11 + 2×4

↠ Perimeter of a sector = 11 + 8

↠ Perimeter of a sector = 19 cm

• Hence, the perimeter of a sector of a circle is 19cm.

Answer 2

$\sf\mathfrak \purple{\underline{Question:-}}$

Find the perimeter of a sector of a circle of radius 4 cm and formed by an arc of measure 11 cm ..

$\sf\mathfrak \blue{\underline{Answer:-}}$

19 CM is the perimeter of the sector .

Explanation :

Perimeter of a Sector = Length of Arc + 2 Radius

Given :

• Length of the arc = 11 cm
• Radius 4 cm

Let the Perimeter be x

➸ x = 11 + 2 (4)

➸ x = 11 + 8

➸ x = 19 cm

Therefore, Perimeter of the arc is 19 cm .
