PLEASE HELP ASAP!!!!

zlopas [31]

Answer:

1)

<u><em>k - 5 = m</em></u>

<u><em>n - 3 = s</em></u>

2)

<u><em>Lisa is 17 and Myra is 12</em></u>

__________________________________________________

<u><em>1) </em></u>Key:

brother = b

me = m/n

sister = s

Equation:

m + 5 = b

m - 3 = s

Answer:

b - k = m

n - 3 = s

<u><em>2)</em></u>

L + M = 19

(L + 5) + M = 29

(L + 5 - 5) + m = 24

L + M = 24 / 2 = 12

L = 12 + 5 = 17

M = 12

Lisa will be 17 and Myra is 12

The volume of a sphere is a function of its radius, V=4/3 πr^3 Evaluate the function for the volume of a volleyball with radius

il63 [147K]

The volume of a volleyball with radius 11.1 cm is 5731.025 cubic centimeter

<h3><u>Solution:</u></h3>

Given that volume of a sphere is a function of its radius

$V=\frac{4}{3} \pi r^{3}$

Radius = 11.1 cm

<em><u>To find: volume of a volleyball</u></em>

Since volleyball is generally of spherical shape, we can use volume of sphere formula

$\text {volume of sphere }=\frac{4}{3} \pi r^{3}$

Where "r" is the radius of sphere and $\pi$ is a constant which has value 3.14

<em><u>Substituting the given radius r = 11.1 cm</u></em>

$\text {volume of sphere }=\frac{4}{3} \times \frac{22}{7} \times 11.1^{3}$

$\text {volume of sphere }=\frac{88}{21} \times 1367.631$

volume of sphere = 5731.025 cubic centimeter

Thus the volume of volleyball is 5731.025 cubic centimeter
