Answer:
Diameter of the circle is 8.4 units
Explanation:
To find the diameter of a circle with area of 56 square units, we will follow the steps below:
write the formula for calculating the area of a circle
area of a circle = πr²
from the question area= 56 units .
π is a constant which is ≈ 3.14
we can now proceed to substitute the values into the formula and solve for r
area of a circle = πr²
56 = 3.14×r²
divide both-side of the equation by 3.14
17.83 = r²
take the square root of both-side
√17.83 = √r²
4.2 =r
r= 4.2 units
but diameter = 2 r
diameter = 2×4.2
diameter = 8.4 units
Diameter of the circle is 8.4 units
