Answer:

$Q=\frac{\pi}{2}*55.5ft=87.18ft\\P=87.18ft*\sqrt{\frac{1}{2}+\frac{16}{\pi ^{2}}}=87.18*0.9515=82.95ft\\$

Step-by-step explanation:

We have a 4-sided triangular pyramid , where

$Q=\frac{\pi}{2}*H\\P=Q*\sqrt{\frac{1}{2}+\frac{4}{\pi ^{2}}}\\Q=\frac{\pi}{2}*55.5ft=87.18ft\\P=87.18ft*\sqrt{\frac{1}{2}+\frac{16}{\pi ^{2}}}=87.18*0.9515=82.95ft\\$

Answer:

The required expression is $\frac{y}{4}-3$ .

The value of the expression when y=20 is 2.

Step-by-step explanation:

Consider the provided phase.

3 less than the quotient of a number y and 4

The quotient of a number y and 4 can be written as: $\frac{y}{4}$

Now 3 less than the quotient of a number y and 4 can be written as:

$\frac{y}{4}-3$

Hence, the required expression is $\frac{y}{4}-3$ .

Now evaluate when y=20.

Substitute y=20 in above expression.

$\frac{20}{4}-3$

$5-3$

$2$

Hence, the value of the expression when y=20 is 2.
