Answer: The radius of the circle is 162 units.
Step-by-step explanation:
The circumference of the circle is given by :-
, where r = radius of the circle.
As per given , we have ,
A circle has a circumference of 1,017.36 units .
From the above formula , we have

Answer:
y=6x+-6
Step-by-step explanation:
Formula to find the area of a triangle = × base × height
For triangles A, B and D, the base occupies 4 squares and the height occupies 4 squares.
Therefore, area = × 4 × 4
= 2 × 4 = 8 sq. units
For triangle E, base occupies 2 squares and height occupies 8 squares.
Therefore, area = × 2 × 8
= 8 sq. units
For triangle C, base occupies 3 squares and height occupies 5 squares.
Therefore, area = × 3 × 5
= 7.5 sq. units
Hence, triangles whose area is 8 sq. units are A, B, D and E.
Answer:
(5)/2
Step-by-step explanation:
sin = opp/hyp
sin(45) = x/5
/2 = x/5
x = (5)/2
