A lake near the arctic circle is covered by a thick sheet of ice during the cold winter months. When spring arrives , the warm air gradually melts the ice , causing its thickness to decrease at a constant rate of 0.2 meters per week. After 7 weeks , the sheet is only 2.4 meters thick

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d
