</span>Give the scientific notation of 8.7 billion.
8.7 billion = 8 700 000 000
Scientific notation is the process of multiplying the given number by 10 to the
power of n.
Since billion has 9 zeros that’s equals
to 10^9
=> 8.7 x 10^9
let’s try solving this
=> 8.7 x (10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10)
=> 8.7 x 1 000 000 000
=> 8 700 000 000
Thus, our scientific notation of 8.7 billion is 8.7 x 10^9</span>
X = 14
1/2 of 14 = 7
7 + 13 = 20
Answer:
12.25 M^2(square) 12.56 M^2(circle)
Step-by-step explanation:
side of square= 3.5 M
area of square garden= side*side
=3.5*3.5
=12.25 M^2
Diameter of circle=4 M
Radius of circle=Diameter/2
=4/2
=2
Area of circle garden= 2(pi)r^2(where r is radius)
=3.14*2*2
=12.56 M^2
