Answer:

15 feet

Step-by-step explanation:

Since this is a square the sides are of the same length.

Now the side multiplied by itself gives 225. Hence the length of the side is a number which multiplied by itself gives 225. It is easy to see that 15 × 15 = 225. Therefore the side is 15 feet long.

katovenus [111]

Answer:

x = - 3

y = 4

Step-by-step explanation:

x + y = 1 | (-3)

x + 3y = 9

- 3x - 3y = - 3

   x + 3y = 9

_____________

- 3x + x = 9 - 3

- 2x = 6

2x = - 6

x = - 3

- 3 + y = 1

y = 1 + 3

y = 4

The roof of a tower in a castle is shaped like a cone. The height of the roof is 30 ft, and the radius of the base is 15 ft. Wha
xz_007 [3.2K]

Answer:

The area of the roof: ≈2287.44 ft^2, the lateral area of the roof:≈1580.58 ft^2

Step-by-step explanation:

The area of the roof is computed by the equation of the area of a cone:
A = πr(r + \sqrt{h^{2}+r^(2) })
(r: radius, h: height, πr^2 is the area of the base of the cone, πr\sqrt{h^{2}+r^(2) } is the lateral area of the cone). So:

A = 15\pi (15 + \sqrt{30^{2} +15^{2}  } ) ≈ 2287.44 ft^2.

As I stated earlier, the lateral area of the roof can be computed:

AL=15\pi \sqrt{30^{2} +15^{2} } ≈ 1580.58 ft^2.
