Area = π * r * r
49 = radius * radius
Radius = 7
Hope this helped☺☺
Answer:
B
Step-by-step explanation:
The coordinates are (0,2) and (2,5).
Use (y2-y1)/(x2-x1).
(5-2)/(2-0).
5-2=3, 2-0=2.
3/2

Step-by-step explanation:
Answer:
The value of x = 14 ...
The value of ∠AED = ( 7x + 15) = 7(14) + 15 = 113
The value of ∠AEB = 5x-3 = 5(14) -3 = 67
Step-by-step explanation:
=> ∠BEC = ∠AED { vertically opposite angles }
∠AED = (7x + 15)°
=> ∠AEB + ∠BEC = 180° { linear pair }
=> ( 5x-3) + ( 7x+15) = 180°
=> 5x -3 + 7x + 15 = 180°
=> 12x + 12 = 180°
=> 12( x +1 ) = 180°
=> x+1 = 180/12
=> x +1 = 15
=> x = 15-1
=> x = 14
