Circumference + perimeter =38
x = circumference of circle
find r in terms of x
2\pir=x
r=\frac{x}{2 \pi }
Area=\pir^2
so..
A=\pi(\frac{x}{2 \pi })^2
=\pi(\frac{x^{2} }{4 \pi ^{2} })
=\frac{x^{2} }{4 \pi }

(38-x) is perimeter
then 
\frac{38-x}{4}
(\frac{38-x}{4})^2
\frac{x^{2} }{4 \pi } + (\frac{38-x}{4})^2
then you graph it and it equals
16.716 cm the circumference of the circle

A solid right pyramid has a square base with an edge length of x cm and a height of y cm. Which expression represents the volume
solniwko [45]

Answer:

Thus, volume of pyramid = \frac{1}{3}x^2y cm³

Step-by-step explanation:

Given: A solid right pyramid has a square base with an edge length of x cm and a height of y cm.

We have to choose from the given options an expression for the volume of the pyramid.

Volume of pyramid = \frac{1}{3}\times Area\ of\ base \times height

Since base is a square with edge length x cm.

Area of square = (side)² = x²

Thus, volume of pyramid = \frac{1}{3}x^2y cm³
