Two kinds of perfume are packaged in square pyramidal bottles. Perfume A is packaged in a bottle with a base of 3 inches square

kondor19780726 [428]

Answer:

The bottle of perfume A contains more glass

Step-by-step explanation:

we know that

The surface area of the square pyramid is equal to the area of the square base plus the area of its four triangular faces

step 1

Find the surface area of Perfume A

$SA=3^{2} +4[\frac{1}{2}(3)(2.5)]=24\ in^{2}$

step 2

Find the surface area of Perfume B

$SA=2.5^{2} +4[\frac{1}{2}(2.5)(3)]=21.25\ in^{2}$

step 3

Compare the surface areas

$24\ in^{2}>21.25\ in^{2}$

therefore

The bottle of perfume A contains more glass

The formula for the area of a circle is A equals xr2 this formula allows you to find the area of a circle if you know the radius

iVinArrow [24]

Answer:

The relation for the area of circle with radius , Diameter , circumference is

A= $\pi$ × radius²

A = $\frac{\pi D^{2} }{4}$

A = $\frac{c^{2} }{4\pi }$

Step-by-step explanation:

Given as :

The formula for the area of circle = $\pi$ × radius²

I.e A = $\pi$ × radius²

Now If we know radius then

Area calculated as A= $\pi$ × radius²

If we know Diameter then

Area calculated as $\pi$ × ( $\dfrac{\textrm Diameter}{2}$ )²

Or, A = $\pi$ × ( $\dfrac{\textrm D}{2}$ )²

I,e A = $\frac{\pi D^{2} }{4}$

If we know the circumference then

∵ circumference = c = 2 × $\pi$ × radius

or, c = 2 × $\pi$ × r

from here we calculate radius

I.e r = $\frac{c}{2\pi }$

And So , Area ( A ) = $\pi$ × radius²

I.e A = $\pi$ × ( $\frac{c}{2\pi }$ )²

Or, A = $\frac{c^{2} }{4\pi }$

Hence The relation for the area of circle with radius , Diameter , circumference is

A= $\pi$ × radius²

A = $\frac{\pi D^{2} }{4}$

A = $\frac{c^{2} }{4\pi }$ Answer
