The length of each side can be found using pythagoras theorem:-
11.3^2 = 2x^2 where x = length od each side
x = sqrt( [11.3^2 / 2)
x = 7.99 meters

Answer:
648 followers
Step-by-step explanation:
Let first day=a1
Tripled followers everyday
Second day=a2=a1×3
Third day=a3=a2*3
Fourth day=a4=a3*3
Fifth day=a5=a4*3
a=8 followers
a2=a1×3
=3*8
=24 followers
a3=a2*3
=24*3
=72 followers
a4=a3*3
=72*3
=216 followers
a5=a4*3
=216*3
=648 followers
On the fifth day, Alex will have a total of 648 followers on his new social media account.
Answer:
The radius of the circle is 5 units
Step-by-step explanation:
Given in the question,
centered point = (-3 , 2)
a point in the circle = (1,5)
To find the radius of circle we will use the circle equation
(x – h)² + (y – k)² = r²,
with the centre being at the point (h, k) and the radius being r.
Plug values in the equation
(1 – (-3))² + (5 – 2)² = r²
(1+3)² + (3)² = r²
4² + 3² = r²
25 = r²
r = √25
r = 5
