Answer:

it would have twice the area of one circle because the radius would double therefore the inside/area would double

Answer:

No

Step-by-step explanation:

no!

Two circles of radius r

= 2(π)(r^2)

= 2π r^2

one circle of radius 2r

= π(2r)^2

= 4π r^2

use an example, eg. r = 3

two circles with r = 3

= 2π(3^2) = 18π

one circle with radius 6

= π(6^2)

= 36π

notice the singe large circle is twice the area of the two smaller ones

A right square pyramid with base edges of length $8\sqrt{2}$ units each and slant edges of length 10 units each is cut by a plan
seropon [69]

Answer:

32 unit^{3}

Step-by-step explanation:

Given:

  • The slant length 10 units
  • A right square pyramid with base edges of length 8\sqrt{2}

Now we use  Pythagoras to get the slant height in the middle of each triangle:

\sqrt{10^{2 - (4\sqrt{2} ^{2} }) } = \sqrt{100 - 32} = \sqrt{68}  units

One again, you can use Pythagoras again to get the perpendicular height of the entire pyramid.

\sqrt{68-(4\sqrt{2} ^{2} )} = \sqrt{68 - 32} = 6 units.

Because slant edges of length 10 units each is cut by a plane that is parallel to its base and 3 units above its base. So we have the other dementions of the small right square pyramid:

  • The height 3 units
  • A right square pyramid with base edges of length 4\sqrt{2}

So the volume of it is:

V  = 1/3 *3* 4\sqrt{2}

= 32 unit^{3}
