The value of the constant of variation is 1/8 if the quantity m varies jointly with p and r when p is 2 and r is 4, m is 1.
<h3>What is directly proportional?</h3>
It is defined as the relationship between two quantity as the one quantity increases the other quantity also increases and vice versa.
We have a quantity m varies jointly with p and r.
Mathematically,
m ∝ p×r
After removing the proportional sign, a constant of proportionality encountered.
Let's c is the constant.
m = c(p×r)
If p = 2, r = 4, and m = 1
1 = c(2×4)
1 = 8c
c = 1/8
Thus, the value of the constant of variation is 1/8 if the quantity m varies jointly with p and r when p is 2 and r is 4, m is 1.

Answer:
True
Step-by-step explanation:
Given data
Diameter =6 yards
Radius R= Diameter/2= 6/2 = 3 yards
R²=3*3=9square yards
Hence R^2 = 9square yards= True
Answer:
75 cm
Step-by-step explanation:
To find the area of a traingle you use the following equation
b*h*.5
We know that the height of the triange is three times the base and that the area is 937.5
This means that
b*3b*.5=937.5
We can combine this and get 1.5b^2=937.5
We can then divide by 1.5 to get b by itself
b^2=625
Then take the square root for our answer and get b=25 (while be also can be -25 it doesn't make sense to have a negative answer in the context of this problem)
So we know that b=25 and that h=3b which means that the height is 75 cm
Find the area of the small circle then the get the radius of the big circle add both radius' (12) . you would use the normal formula to find the area of the big circle as well . you should get your answer that way !
