Answer:
1.5
Step-by-step explanation:
a : b = 1 : 12/5
Area of a circle = πr²
Where : = π = pi = 22/7
R = radius
Let the radius of circle a = 1
Area of circle A = 1π
Radius of circle A = square root of 12/5 = 1.5
The circumference of a circle = 2nr
n = 3.14
circumference of circle A = 2 x n x 1 = 2n
circumference of circle B = 2 x n x 1.5 = 3n
ratio of circumference = 3n / 2n = 1.5
Show that the co-interior should equal to 360 degrees
Answer:
Step-by-step explanation:
This is how you find it
1) Substitute the p into the equation to get 7(-7)-7=-56. Then you get -49-7=-56. This is true
Hope this helps! :)
Answer:
Step-by-step explanation:
If f(x)=x²
g(x) = (3x)²
because : g(0)=0 and g(1)= (3×1)² =3 passes through A(1;3) and O(0;0).
Answer:
3x-26=2x(because they are vertical angle)
or,3x-2x=26
therefore x=26
