Answer:

(A). 2

Step-by-step explanation:

FYI :

$\int\limits^4_1 {x^{-\frac{1}{2} } } \, dx$ = 2√x (from 1 to 4) = 2√4 - 2√1 = 2

A sphere has a radius of 11 feet. A second sphere has a radius of 8 feet. what is the difference of the volume of thespheres

Veronika [31]

The difference between the volume of the spheres is 3428.88 cubic feet

Explanation:

Given that one sphere has a radius of 11 feet.

A second sphere has a radius of 8 feet.

Volume of the 1st sphere:

The formula to determine the volume of the sphere is given by

$V=\frac{4}{3} \pi r^3$

Volume of the 1st sphere is given by

$V=\frac{4}{3}(3.14)(11)^3$

$V=\frac{4}{3}(3.14)(1331)$

$V=\frac{16717.36}{3}$

$V=5572.45$

The volume of the 1st sphere is 5572.45 cubic feet.

Volume of the 2nd sphere:

Volume of the 2nd sphere is given by

$V=\frac{4}{3}(3.14)(8)^3$

$V=\frac{4}{3}(3.14)(512)$

$V=\frac{6430.72}{3}$

$V=2143.57$

The volume of the 2nd sphere is 2143.57 cubic feet.

Difference between the volume of the two spheres:

Difference = Volume of the 1st sphere - Volume of the 2nd sphere

= 5572.45 - 2143.57

Difference = 3428.88 cubic feet.

Hence, the difference between the volume of the spheres is 3428.88 cubic feet.

Please I need help with this problem number 5????

zheka24 [161]

Estimating the area:
$x = (20 \times 8)(13 \times 8) \\ x = 264$
Calculating wallpaper:
$x = (264 \times 1.05) \div 35 \\ x = 7.92 \\ x = 8$
we round up here because they will need a full roll to complete the room. Since they can't buy 7.92 rolls, they must buy 8.

Calculating cost:
$x = 8(31.48) + 31.48(0.0825) \\ x = 254.44$
