The situation forms the right triangle above:

Where x is the length of the ladder.

Apply the Pythagorean theorem:

c^2 = a^2 +b^1

where:

c = hypotenuse = longest side = x

A &b = the other 2 legs of the triangle

Replacing:

x^2 = 60^2 + 15^2

Solve for x

x^2 = 3,600 + 225

x^2 = 3,825

x =√3,825

x = 61.85 ft

mezya [45]

Answer:

5/8

Step-by-step explanation:

The sectors are labeled 1,2,3,4,5,6,7,8

Numbers less than 4: 1,2,3

Multiples of 4: 4,8

We are looking for 1,2,3,4,8  = 5 choices

What is the diameter of a hemisphere with a volume of 2233\text{ cm}^3,2233 cm 3 , to the nearest tenth of a centimeter?
Agata [3.3K]

Answer:

The diameter of the hemisphere is 20.4 centimeters.

Step-by-step explanation:

The volume of an hemisphere is given by:

V = \frac{2 \pi r^{3}}{3}

In this problem, we have that:

V = 2233

So

\frac{2 \pi r^{3}}{3} = 2233

2\pi r^{3} = 3*2233

r^{3} = \frac{3*2233}{2\pi}

r = \sqrt[3]{\frac{3*2233}{2\pi}}

r = 10.2

The radius is 10.2 centimeters.

The diameter is double the radius. So:

2*10.2 = 20.4

The diameter of the hemisphere is 20.4 centimeters.
