I would say the answer is a
To find the diameter, find the circumference, i.e the length covered in one revolution, and then subject the diameter from formulas.
Circumference = 3.6 ÷ 18 = 0.2m = 2πr
πr = 0.2 ÷ 2 = 0.1
r = 0.1 ÷ (22/7) = (0.1 * 7) ÷ 22 = 0.7 ÷ 22
r = 0.0318
Diameter = 2r
Diameter = 2 * 0.0318 = 0.0636m ...//Ans ...
Answer:
Triangle ABE and triangle CDE are congruent by using SAS theorem.
Step-by-step explanation:
It is given that e is the midpoint of BD and
.
(E is midpoint of BD)
Angle AEB and angle CED are vertical opposite angle and the vertical opposite angles are always same.

(Given)
So by using SAS theorem of congruent triangles.

Therefore triangle ABE and triangle CDE are congruent by using SAS theorem.
