Answer: 39.58 cm
Step-by-step explanation:
The circumference of a circle is 2 times the radius times pi or pi times the diameter. so we know the diameter is 12.6 so just multiply it by pie.
12.6 * pi = 39.584
Now rounded to the nearest hundredth is 39.58.
Answer:the diameter is 7
Step-by-step explanation: 21.98 divide by pi is 7 so diameter is 7
Answer:
width : x+4
Step-by-step explanation:
(x+9)(x+4) = x^2+4x+9x+36
x^2+13x+36
think of numbers that multiply together to get 36
and of those number, what numbers add up to 13
9 times 4 equals 36
9 plus 4 equals 13

Answer:
The correct option is;
[B] ΔABF ≅ ΔEDF
Step-by-step explanation:
GIven that ∠FAE is congruent to ∠FEA
Therefore, triangle ΔFAE is an isosceles triangle (Definition of isosceles triangle)
Segment FA is equal to segment FE (Equal segments of isosceles triangle)
Angle ∠EFD is congruent to angle ∠AFB (Vertically opposite angles)
Therefore, triangle ΔABF is congruent to triangle ΔEDF (Angle Angle Side AAS rule of congruency)
The correct option is ΔABF ≅ ΔEDF.
