On planet korba, a solar blast has melted the ice caps on its equator. 9 years after the ice melts, tiny planetoids called echina start growing on the rocks. Echina grows in the form of circle, and the relationship between the diameter of this circle and the age of echina is given by the formula d = 4*v (t-9) for t = 9 where d represents the diameter in mm and t the number of years since the solar blast.Jagan recorded the radius of some echina at a particular spot as 7mm. How many years back did the solar blast occur?
- a)21.25
- b)15
- c)12.25
- d)14.05
Correct answer is option 'A'. Can you explain this answer?

Verified Answer
On planet korba, a solar blast has melted the ice caps on its equator....
d = 4*(t-9)
Given r = 12 mm
So, d = 24 mm
So,
24 = 4t - 36
4t = 60
t = 15 years

On planet korba, a solar blast has melted the ice caps on its equator....
The correct option is Option A.
r = 7
d = 14
Also, d =4 × (t-9)
So, 14 = 4t - 36
t = 12.25
Now, the plant starts growing after 9 years of blast.
So, 12.25 + 9 = 21.25

On planet korba, a solar blast has melted the ice caps on its equator....
Given Information:
- On planet Korba, a solar blast has melted the ice caps on its equator.
- 9 years after the ice melts, tiny planetoids called echina start growing on the rocks.
- The relationship between the diameter of echina and its age is given by the formula d = 4*v(t-9) for t = 9, where d represents the diameter in mm and t represents the number of years since the solar blast.
Objective:
To calculate the number of years since the solar blast occurred.
Approach:
1. Use the given formula d = 4*v(t-9) to find the value of t when the radius is 7mm.
2. Use the formula for the radius of a circle, r = d/2, to calculate the radius of echina.
3. Substitute the value of the radius into the formula from step 1 and solve for t.
4. The resulting value of t will represent the number of years since the solar blast occurred.
Calculation:
Given formula: d = 4*v(t-9)
Step 1: Finding the value of t when the radius is 7mm
- Given radius, r = 7mm
- Using the formula for the radius of a circle, r = d/2, we can find the diameter, d = 2*r
- Substitute the value of d into the given formula: 2*r = 4*v(t-9)
- Simplify the equation: 2*7 = 4*v(t-9)
- 14 = 4*v(t-9)
Step 2: Calculate the radius of echina
- Given radius, r = 7mm
Step 3: Substitute the value of the radius into the formula from step 1 and solve for t
- 14 = 4*v(t-9)
- Divide both sides of the equation by 4: 14/4 = v(t-9)
- Simplify: 3.5 = v(t-9)
- Divide both sides of the equation by v: 3.5/v = t-9
- Add 9 to both sides of the equation: 3.5/v + 9 = t
Step 4: Calculate the number of years since the solar blast occurred
- Substitute the value of v (given as 3.14) into the equation: 3.5/3.14 + 9 = t
- Simplify: 1.114+9 = t
- t = 10.114
Therefore, the solar blast occurred approximately 10.114 years ago.
Final Answer:
The solar blast occurred approximately 10.114 years ago.
