Estimate the radius of the object
Anvisha [2.4K]

Answer:

r = 1.41 mm

Step-by-step explanation:

Given that,

The circumference of the flower, C = 8.9 mm

We need to find its radius. We know that,

Circumference, C=2\pi r

Where

r is the radius of the object

r=\dfrac{C}{2\pi}\\\\r=\dfrac{8.9}{2\pi}\\\\r=1.41\ mm

So, the radius of the object is equal to 1.41 mm.

What is the length of the figure?
nadezda [96]
There are two ways to do this. One is by adding up the squares, which takes a while. The other way is if you notice that the length along the bottom is the same as that long the top, and the same is true for the sides. While it does not appear this way at first, imagine that that was the floor plan of a house. If you looked at it from the side, you wouldn't see the dent in the corner, only one side. Since the length of the top is 13 units, from -7 to 6, and the side is also 13 units, from -6 to 7, the answer is 13*2 + 13* 2 = 26 + 26 = 52

52 units long.

PLEASE HELP 100 POINTS!
krok68 [10]

Answer:

800%

Step-by-step explanation:

<u>Volume of a square based pyramid</u>

\sf V=\dfrac{1}{3}a^2h

where:

  • a = base side length
  • h = height

<u>Given values</u> for Pyramid A:

  • a = 14 inches
  • h = 6 inches

Substitute the given values into the formula to find the volume of <u>Pyramid A</u>:

\begin{aligned}\textsf{Volume of Pyramid A} & = \sf \dfrac{1}{3}(14)^2(6)\\\\& = \sf \dfrac{1176}{3}\\\\& = \sf 392\:\: in^3 \end{aligned}

Given:

  • Volume of Pyramid B = 3136 in³

To find how many times bigger Pyramid B is than Pyramid A, divide the <u>volume of Pyramid B</u> by the <u>volume of Pyramid A</u>:

\implies \sf \dfrac{3136}{392}=8

Therefore, the volume of Pyramid B is 8 times bigger than the volume of Pyramid A.

8 as a percentage is 800%, since 800/100 = 8.

Therefore, the volume of Pyramid B is 800% the volume of Pyramid A.

To verify this, find 800% of the volume of Pyramid A:

⇒ 800% of 392

= 800/100 × 392

= 8 × 392

= 3136

Find the percent of the number.<br> 30% of 30 is<br> Explain your method.
nirvana33 [79]

Answer:

The answer would be 9

Step-by-step explanation:

Step 1: Our output value is 30.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$30=100\%$.

Step 4: Similarly, $x=30\%$.

Step 5: This results in a pair of simple equations:

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

Step 7: Again, the reciprocal of both sides gives

Therefore, 30% of 30 is 9
