For properties of logarithm we have the following:
 loga (x ^ b) = b * loga (x)
 Therefore, following this property we have for this case:
 log3 (x ^ 9) = 9log3 (x)

A round cake has a diameter of 30\text{ cm}30 cm30, start text, space, c, m, end text. Angela places the cake on a circular cake
VLD [36.1K]

Answer:

The circumference of the cake board is <u>35π cm</u>.

Step-by-step explanation:

The question is incomplete, so the complete question is below:

A round cake has a diameter of 30 cm. Angela places the cake on a circular cake board with a diameter 5 cm longer than that of the cake. What is the circumference of the cake board? Give your answer in terms of π.

Now, to find the circumference of the cake board.

As, given diameter of cake = 30 cm.

And diameter of cake board is 5 cm longer than that of the cake.

Thus, the diameter of cake board is:

30\ cm+5\ cm=35\ cm.

So, to find the circumference we need radius, by putting formula:

Radius(r)=\frac{Diameter}{2}

Radius(r)=\frac{35}{2}

Radius(r)=17.5\ cm.

Now, to get the circumference of the cake board we put formula:

Circumference=2\pi r.

Circumference=2\times \pi \times 17.5

Circumference=35\pi \ cm.

Therefore, the circumference of the cake board is 35π cm.

What is the perimeter of a parallelogram with base 32 cm, side length 34 cm, and height 19 cm?
Serjik [45]

Answer:

p=132cm^2

Step-by-step explanation:

Given the following question:

Formula for perimeter:

2(s+b)

We are given a base and a length for this parallelogram. So, to find the perimeter we simply have to substitute the values into the formula and solve.

2(s+b)
2(34+32)
34+32=66
2(66)
2(66)=2\times66=132
p=132cm^2

Hope this helps.

What is the surface area of the solid?
Paha777 [63]

Answer:

  D.  28 square centimeters

Step-by-step explanation:

The surface area of the prism is the sum of the base areas and the lateral area. Here, the base is an odd shape, so it must be decomposed into shapes we can find the area of.

__

<h3>base area</h3>

The base of this prism is the L-shaped face nearest the observer. It can be decomposed into a 1 cm square atop a 1 cm by 3 cm rectangle. The area of the face is the sum of the areas of these parts.

  square area = s² . . . . where s is the side length

  = (1 cm)² = 1 cm²

  rectangle area = bh . . . . b is the base, h is the height

  = (3 cm)(1 cm) = 3 cm²

Then the area of the one prism base we see is ...

  base area = 1 cm² +3 cm² = 4 cm²

The total area of both L-shaped bases of the prism is ...

  total base area = 2(4 cm²) = 8 cm²

__

<h3>lateral area</h3>

The perimeter of the base is the sum of the lengths of its edges. Working clockwise from the lower left corner, we find the base perimeter to be ...

  (1 +2 +1 +1 +2 +3) cm = 10 cm

The lateral area is the product of the "height" of the prism (the distance between the parallel bases) and this perimeter length.

  LA = Ph

  LA = (10 cm)(2 cm) = 20 cm²

__

<h3>solid area</h3>

The surface area of the solid is the sum of the areas of the bases and the lateral area:

  total surface area = total base area + LA

  = (8 cm²) +(20 cm²) = 28 cm²

The surface area of the solid is 28 square centimeters.
