Answer:

C

Step-by-step explanation:

do that with pithagoras:

20² + 4,5² = x²

400 + 20,25 = x²

420,25 = x²

x = \sqrt{420,25}

x ~ 20,5

Letter C: 20,5 feet

Answer:

14.13 in³

Step-by-step explanation:

Volume of a ball (sphere) is:

V = ⁴/₃ π r³

Circumference of a ball (circle) is:

C = 2π r

Use the circumference to find the radius.

9.42 in = 2π r

r = 1.50 in

Use the radius to find the volume:

V = ⁴/₃ π (1.50 in)³

V = 14.13 in³

Find the geometric mean between each pair of numbers. sq root 49 and sq root841
vodomira [7]

<u>Answer:</u>

The geometric mean between each pair of numbers \bold{\sqrt{49} \text { and } \sqrt{841} \text { is } 14.24}

<u>Solution:</u>

The Geometric mean between two numbers a and b is given as  Geometric mean = \bold{\sqrt{ab}}   --- eqn 1

The Geometric Mean is a special type of average where we multiply the numbers together and then take a square root for the numbers.

From question, given that two numbers are \sqrt{49} and \sqrt{841}

Hence we can say “a” = \sqrt{49} =7  

Similarly “b” = \sqrt{841} = 29  

We have to find the geometric mean between “7” and “29”

By using equation 1,  

Geometric mean between 7 and 29 = \sqrt{7 \times 29} = \sqrt{203} = 14.24

Hence the geometric mean between \sqrt{49} \text { and } \sqrt{841} \text { is } 14.24
