Answer: The answer is (d) It is an irrational number.
Step-by-step explanation: Given formula for circumference of a circle is

where 'd' is the length of the diameter and a rational number.
We are to choose one of the given four options for the circumference 'c' of the circle.
We know that the circumference of a circle with diameter 'd' is given by

Comparing this with the given equation, we get

Now, the product of a rational and an irrational number is again irrational, so 'r × d' will be an irrational number.
Hence, the circumference, c = rd is irrational.
Thus, the correct option is (d) It is an irrational number.

Answer:
Point T = (4,9)
Step-by-step explanation:
Given:
S (−5,0)
M (10, 15)
m1:m2 = 3:2
Find:
Point T
Computation:
X = [m1x2 + m2x1] / [m1+m2]
Y = [m1y2 + m2y1] / [m1+m2]
X = [(3)(10) + (2)(-5)] / [3+2]
Y = [(3)(15) + (2)(0)] / [3+2]
X = 20 / 5 = 4
Y = 45 / 5 = 9
Point T = (4,9)
