Question

A volcanic eruption ejects about $43,600,000,000$cubic feet of volcanic rock. A smaller volcanic eruption ejects about $75\%$of this amount. What is the approximate amount of volcanic rock that the smaller volcanic eruption ejects?

Answer 1

Given, A volcanic eruption ejects about $43,600,000,000$cubic feet of volcanic rock.

A smaller volcanic eruption ejects about $75\%$of this amount.

Approximate amount of volcanic rock that the smaller volcanic eruption ejects $=\frac{75}{100}\times 43,600,000,000$

$=75\times 43,600,000,000$

$=3,270,000,000,000$
