The radius of the large sphere is double the radius of the small sphere.

Vlad [161]

Answer:

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Remember that all the spheres are similar

Let

z ----> the scale factor

V_1 ---> the volume of the large sphere

V_2 ---> the volume of the small sphere

$z^3=\frac{V_1}{V_2}$

<em>Find the scale factor</em>

we know that

The radius of the large sphere is double the radius of the small sphere

The scale factor is 2

$z=2$

substitute the value oz z

$z^3=\frac{V_1}{V_2}$

$2^3=\frac{V_1}{V_2}$

$8=\frac{V_1}{V_2}$

$V_1=8V_2$

The volume of the large sphere is 8 times the volume of the small sphere

Find the surface area of a regualar pyramid that is a pentagonal pyramid with the area of a base is is 440.4mm and a height of 2

Inessa [10]

Answer:

1240.4 mm²

Step-by-step explanation:

The surface area of a pyramid = Area of the all sides + Area of base

Each side is a triangle.

With a regular pentagonal pyramid, the area of each triangle is

$A = \frac{1}{2}\times\text{base}\times\text{slant height}$

For the 5 triangles,

$A = 5\times\frac{1}{2}\times\text{base}\times\text{slant height} = \frac{1}{2}\times5\times\text{base}\times\text{slant height}$

Substituting given values,

$A = 5\times\frac{1}{2}\times16\ \text{mm}\times20\ \text{mm} = 800 \text{mm}^2$

Area of base = 440.4 mm²

Surface area of a pyramid = 800 + 440.4 mm² = 1240.4 mm²

Solve 2x-11 = k for x

LenKa [72]

2x-11 = k

add 11 to each side

2x-11+11 = k+11

2x = k+11

divide each side by 2

x = (k+11)/2
