The burning of coal can and will irritate the lungs
To find the circumference we must work backwards from the area to find the radius of the circle.
Area = pi x radius squared
4 x pi = pi x radius squared
4 = radius squared
2 = radius
Now that we have the radius, we can plug it into our formula for circumference.
Circumference = pi x diameter (or 2 x radius)
Circumference = pi x 4
Circumference = 4

Answer: The expected ratio would be 1:2:1.
Explanation: In a dihybrid cross, an organism with two different characteristics crosses with another organism with other two different characteristics. In this question, for example, the doubly heterozygous agouti mouse is represented by AaBb and the doubly homozygous recessive white mouse is aabb. So crossing them, we'll have
ab
AB AaBb (agouti)
Ab Aabb (black fur)
aB aaBb (albino)
ab aabb (albino)
Analising the table, there is 1 in 4 chances of a agouti; 1 in 4 chances of a black fur and 1 in 2 chances of an albino, therefore, the ratio is 1:2:1.
