Question

find the area of a sector of a circle with radius 6 cm if angle of sector is 90 degree​

Answer 1

Answer :

• The area of sector of circle is 88/7 cm²

Given :

• Radius = 6cm
• Angle of sector is 90 degree

To find :

• Area of sector of circle

Solution :

Given that,

• Radius (r) = 6cm
• Angle of sector θ = 90⁰

As we know that,

• Area of sector of circle = θ/360⁰ × πr²

where, θ is 90⁰ and r is 6cm

》θ/360⁰ × πr²

》90/360⁰ × 22/7 × (6)²

》1/4 × 22/7 × 36

》4 × 22 / 7

》88/7 cm²

Hence , The area of sector of circle is 88/7 cm²

Answer 2

Answer:

198cm²

Step-by-step explanation:

according to above solution

from 1/4×22/7×36

=22/7×9

=22×9/7

=198/7cm²
