What is the difference in surface areas, in square feet, of the two boxes?

Katarina [22]

The difference is 3ft since the surface area for the prism is 57, and the surface area for the cube is 54.

You can use the surface area formula
2(wl+hl+hw) = Area
2·(3·4.5+2·4.5+2·3)=57

And a cubes surface area formula
6a^2 = Area
6·32=54

In a circle of diameter 30 cm a chord of 10cm is drawn. To 2 decimal places, how far is the chord from the center of the circle?

Romashka-Z-Leto [24]

<u>Given:</u>

The circle has a diameter of 30 cm and a chord of 10 cm is drawn.

Radius of the circle = 15 cm

Half of the chord = 5 cm

We need to determine the distance of chord from the center of the circle.

<u>Distance of chord from the center of the circle:</u>

Let us use the Pythagorean theorem, to find the distance between the center and the chord.

Let d denote the distance between the center and the chord of the circle.

Thus, we get;

$15^2=d^2+5^2$

$225=d^2+25$

$200=d^2$

Taking square root on both sides, we get;

$14.14=d$

Thus, the distance between the center and the chord of the circle is 14.14 cm.

Hence, Option A is the correct answer.

Plz answer question I’m the picture

Stells [14]

Answer:

x = 13.5

BC = 30

Step-by-step explanation:

BC is double the length of DE. And we know that DE is equal to 15. So 15 x 2 is 30.

Now to find x. We know that our answer has to add up to 30. So we first subtract 3 from 30 to get 27. Then divide 27 by 2 to get what x is equal to. x = 13.5
