<u>Given</u>:

Given that the side length of the base of the square pyramid is 16 inches.

The height of the pyramid is 22.1 inches.

We need to determine the volume of the square pyramid.

<u>Volume of the square pyramid:</u>

The volume of the square pyramid can be determined using the formula,

V=\frac{1}{3}Bh

where B is the area of the base and h is the height of the pyramid.

Substituting B = (16 × 16) and h = 22.1, we get;

V=\frac{1}{3}(16 \times 16)(22.1)

V=\frac{1}{3}(256)(22.1)

V=\frac{1}{3}(5657.6)

V=1885.9

Thus, the volume of the pyramid is 1885.9 cubic inches.

Nadya [2.5K]

Answer:

The probability that the average score of the 49 golfers exceeded 62 is 0.3897

Step-by-step explanation:

The average score of all golfers for a particular course has a mean of 61 and a standard deviation of 3.5

\mu = 61

\sigma = 3.5

We are supposed to find he probability that the average score of the 49 golfers exceeded 62.

Formula : Z=\frac{x-\mu}{\sigma}

Z=\frac{62-61}{3.5}

Z=0.285

Refer the z table for p value

p value = 0.6103

P(x>62)=1-P(x<62)=1-0.6103=0.3897

Hence the probability that the average score of the 49 golfers exceeded 62 is 0.3897

Umference of a Circle: Mastery Test
sasho [114]

Answer:

•26.376 units

•23.236 units

•34.54 units

•59.66 units

Step-by-step explanation:

The formula for the circumference of a circle is ...

 C = 2πr = πd

 C = 2(3.14)r = 6.28r   or   C = 3.14d

 where r is the radius and d is the diameter.

Put the given radius or diameter into the relevant formula and compute the product. The results are all in "units".

 r = 4.2   ⇒   C = 6.28×4.2 = 26.376

 d = 7.4   ⇒   C = 3.14×7.4 = 23.236

 d = 11   ⇒   C = 3.14×11 = 34.54

 r = 9.5   ⇒   C = 6.28×9.5 = 59.66
