Which ratios approximate pi ()?

kramer

9514 1404 393

Answer:

A: 66/21

E: 22/7

Step-by-step explanation:

The offered choices reduce to 3 1/7 or to 3. The best approximations of those given are the ones that reduce to 3 1/7.

A: 66/21 = 22/7 = 3 1/7

B: 60/20 = 3

C: 21/7 = 3

D: 45/15 = 3

E: 22/7 = 3 1/7

___

<em>Comment on pi approximations</em>

The ratio 22/7 differs from π by about 0.04%. A better approximation is 355/113, which differs from π by about 0.000008%. The approximation 3.14 differs from π by about 0.05%.

Answer:

a = -4.

Step-by-step explanation:

25(√5)^a * (√5) ^3 = 5√5

25*5^a/2 * 5^3/2 = 5*5^1/2

25*5^a/2 = 5*5^1/2 / 5^3/2

25*5^a/2 = 5^1 *5^1/2 / 5^3/2

25*5^a/2 = 5^3/2 / 5^3/2 = 1

5^a/2 = 1/25 = 5^-2

The bases are equal, so

a/2 = -2

a = -4.

The pyramid below has a square base.

zavuch27 [327]

The volume of the pyramid would be 2406.16 cubic cm.

<h3>How to find the volume of a square-based right pyramid?</h3>

Supposing that:

The length of the sides of the square base of the pyramid has = b units

The height of the considered square-based pyramid = h units,

The pyramid below has a square base.

h = 24.4 cm

b = 17.2 cm

Then, its volume is given by:

$V = \dfrac{1}{3} \times b^2 \times h \: \rm unit^3$

$V = \dfrac{1}{3} \times 17.2^2 \times 24.4 \: \rm unit^3\\\\V = 2406.16$

Therefore, the volume of the pyramid would be 2406.16 cubic cm.
