Answer:
6km
Step-by-step explanation:
Area of circle = πr²
Where r = radius, π= 3.14, A = 28.26km²
A = 3.14 x r²
3.14 r2 = 28.26
Divide both sides by 3.14
r²= 28.26/3.14
r² = 9
Square root both sides
r= √9
r= 3
Radius = 3km
Note : Diameter = 2 x radius
Diameter = 3 x 2
Diameter = 6km

Answer:
59
Solution
Equation 7x^2 + 2y=0
Where x=1,y=5
Put the value of x and y in equation
⟹(7×1)^2 + 2×5
⟹49+10
=59
Answer:
4%
Step-by-step explanation:
To solve this problem we can use a modified version of the simple interest formula which is shown below:
<em>P = initial balance</em>
<em>I = interest</em>
<em>t = time</em>
<em />
Plug the values into the equation:
The last step is to convert 0.04 into a percent:
0.04(100) = 4
The interest rate is 4%.
Answer:
