Answer 1

Question: Find the area of a quadrant of a circle whose arc length is 11 cm.

Select one:

cm2

77 cm

7 cm

7 cm²

we have

• C = 22cm
• 2πr = 22cm

• 2×22/7 ​×r = 22

• r=3.5cm

Now,

• area of the quadrant of a circle = πr²

• 22/7 × (3.5)²/4

• 22 × 12.25/28

• 9.625cm²

therfore area of the quadrant of a circle is  9.625cm²
