The equation 890 = 1/3 B(46) can be used to find the area of the circular base .
What is Area ?
Area is the space enclosed within the perimeter of the given shape.
It is given in the question that Area of the base of a volcano has to be determined.
The structure of a volcano is that of a Cone
Area of a conical structure is given by
V = (1/3) * height * (radius)²
890 = 1/3 (radius)²(46)
V = 890 h = 46
area of a circle = π (radius)²,
890 = 1/3 B(46)
If B = (radius)²
Therefore Option D is the correct answer
890 = 1/3 B(46) equation can be used to find the area of the circular base .
