Ivan wants to fill with foam the empty space left in a cube-shaped box after he places a basketball in the box. How many cubic i
Ann [662]

Answer:

280 cubic inches

Step-by-step explanation:

Cubic inches of foam required = volume of the box - volume of the basketball

The box has a shape of a cube, so that;

volume of the box = l^{3}

where l is the length of the sides of the box.

volume of the box = 9^{3}

                               = 729 cubic inches

volume of the box = 729 cubic inches

The basketball has the shape of a sphere, so that;

volume of the basketball = \frac{4}{3} \pir^{3}

                                          = \frac{4}{3} x 3.14 x (4.75)^{3}

                                           = 448.693

volume of the basketball = 448.693 cubic inches

Thus,

cubic inches of foam required = 729 - 448.693

                                                   = 280.307

The cubic inches of foam to be used is 280 cubic inches.

Sidana [21]

Answer:

Area of ΔDEF = 12 in²

Step-by-step explanation:

Since they are similar, we have to find the scale factor

Scale Factor = \frac{Side OfDilated Triangle}{Side of Original Triangle}

Scale Factor = 4/2

Scale Factor = 2

<u><em>This means The area of ΔABC is 2 times the area of ΔDEF</em></u>

So,

ΔABC = 2(ΔDEF)

Where Area of ΔABC = 24 in²

24 = 2(ΔDEF)

Dividing both sides by 2

=> Area of ΔDEF = 12 in²
