Answer: First option

Step-by-step explanation:

1. You must apply the following formula for calculate the volume of a square pyramid:

V=\frac{b^{2}*h}{3}

Where h is the height and b is a side of the base.

2. Calculate the height by applying the Pythagorean Theorem:

h=\sqrt{(15m)^{2}-(\frac{18m}{2} )^{2}}=12m

3. Therefore, the volume is:

V=\frac{(18m)^{2}*12m}{3}=1296m^{3}

Consider two circular swimming pools. Pool A has a radius of 22 feet, and Pool B has a diameter of 13.6 meters. Complete the des
maw [93]

Answers:

13 42 m; B; 0.57 m

Step-by-step explanation:

Data:

Pool A:  r = 22 ft

Pool B: D = 13.6 m  

Calculations:

1. Radius of Pool A

r = 22 ft × (0.305 m/1 ft) = 6.71 m

2. Diameter of Pool A

D =2r = 2 × 6.71 = 13.42 m

The diameter of Pool A is 13.42 m.

3. Compare pool diameters

The diameter of Pool B is 13.6 m.

So, the diameter of Pool <u>B</u> is greater.

4. Compare circumferences

The formula for the circumference of a circle is

C = 2πr or C = πD

Pool A: C = 2π × 6.71 = 42.16 m

Pool B: r =    π × 13.6 = 42.73 m

Pool B - Pool A = 42.73 - 42.16 = <u>0.57 m </u>

The circumference is greater by <u>0.57 m.</u>
