Question:

Karina has recently begun kickboxing and purchased training equipment as modeled in the diagram below. The cylindrical base is 15 inches tall with a diameter of 22 inches.

Karina wants to fill the base so that it is 85% full. What is the volume of the base that she is filling? (Find 85% of the volume).

Answer:

$Section = 4847.3205\ in^3$

Step-by-step explanation:

Given

$h = 15in$ -- height

$d = 22in$ -- diameter

Required

85% of the volume

First, calculate the radius

$r = \frac{1}{2} * d$

$r = \frac{1}{2} * 22= 11in$

The volume (V) is then calculated using:

$V = \pi r^2h$

$V = 3.142* 11^2 * 15$

$V = 5702.73\ in^3$

85% of the volume is:

$Section = 85\% * V$

$Section = 85\% * 5702.73\ in^3$

$Section = 4847.3205\ in^3$

Alchen [17]

30 = 5(m) + 7(n)

5(a) + 30 = 7(a)

(a) is the number of visits!

15 = (a)

5(15) = 75 + 30 = 7(15) = $105

What is the value of a in the equation 5a -10b = 45 when b = 3

leva [86]

Salutations!

$5a-10b = 45$

value of $b = 3$

Multiply 10 and 3

$10*3=30$

Now, you can solve the equation --

$5a-30=45$

separate the variables aside, and the numbers aside.

$5a=45 +30$

$5a=75$

$a=75/5$

$a=15$

Hope I helped (:

Have a great day!
