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

<u>Now If we know radius then </u>

Area calculated as A=   \pi × radius²

<u>If we know Diameter then</u>

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}

<u>If we know the circumference then</u>

∵ 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
