24- sqrt(720/4) divide 720 by 4
24 - sqrt (180) now break down 180 to 9*4*5
24- sqrt(9) *sqrt(4) *sqrt (5) so 9becomes 3, 4 becomes 2
24- 3*2*sqrt(5) multiply 3 and 2
24-6sqrt(5)
Answer:
Step-by-step explanation:
This figure is quarter of a circle.
=> Perimeter = π/2r + 2r
=> 5π + 10
=> 5(3.14) + 10
=> 15.7 + 10
=> 26 units
Area = πr²/4
=> 3.14 x 100 / 4
=> 25 x 3.14
=> 79 sq. units
Answer: x < -3
Step-by-step explanation: Hope this helped!!
