A leather ball has a diameter of 28.4 cm. Which is the area of the piece of leather used on the surface of the ball?

Ira Lisetskai [31]

Answer:

$A=806.56\pi\ cm^2$

Step-by-step explanation:

Given that,

The diameter of a leather ball, d = 28.4 cm

Radius, r = 14.2 cm

We need to find the area of the piece of leather used on the surface of the ball. The surface area of the ball is given by :

$A=4\pi r^2\\\\A=4\times \pi\times (14.2)^2\\\\A=806.56\pi\ cm^2$

So, the area of the piece of leather is $806.56\pi\ cm^2$ . The correct option is (b).

A 10-foot ladder leans against a wall so that it is 6 feet high at the top. The ladder is moved so that the base of the ladder t

konstantin123 [22]

Answer:

The top of the ladder is now at 10 ft.

Step-by-step explanation:

At the start, we have a height H=6, a length L=10 and a base B, that has to be calculated by the Pythagorean theorem:

$B^2=L^2-H^2=10^2-6^2=100-36=64\\\\B=\sqrt{64}=8$

The base is moved twice the distance the height moves up.

We called this distance x, so we have:

$L^2=(H+x)^2+(B-2x)^2=H^2+2Hx+x^2+B^2-4Bx+4x^2\\\\L^2=(H^2+B^2)+5x^2+(2H-4B)x\\\\L^2=L^2+5x^2+(2H-4B)x\\\\0=5x^2+(2H-4B)x\\\\5x+(2H-4B)=0\\\\x=\dfrac{4B-2H}{5}=\dfrac{4*8-2*6}{5}=\dfrac{32-12}{5}=\dfrac{20}{5}=4$

The new height (H+x) is

$H'=H+x=6+4=10$

The base travels 2x=8, so the new base B' is 0.

This means that the ladder is all against the wall (L=H').

Referring to the figure, find the value of x

olga2289 [7]

Answer:

x = 183

Step-by-step explanation:

(x -73)° + x° +67° = 360°

x-73+ x +67 = 360

x + x -73 +67 = 360

2x-6 = 360

2x = 360+6

x = 366÷2

x = 183

Check:

(183 - 73) = 110° , x = 183° , 67°

110° + 183° + 67° = 360°
