Answer:

9π m ≈ 28.27m

Step-by-step explanation:

The volume of a right cylinder is given by the formula

πr²h where r is the radius of the base of the cylinder(which is a circle), h is the height of the cylinder

Circumference of base of cylinder is given by the formula 2πr

Given,

2πr = 4m

r = 2/π m

Volume given as 36 m³

So πr²h = 36
π (2/π)² h = 36

π x 4/π² h = 36

(4/π) h = 36

h = 36π/4 = 9π ≈ 28.27m

<u>Answer:</u>

h = \bf 28.3 \space\ m

<u>Step-by-step explanation:</u>

• We are given:

○ Volume = 36 m³,

○ Circumference = 4 m

• Let's find the radius of the cylinder first:

\mathrm{Circumference} = 2 \pi r

Solving for r :

⇒ 4 = 2 \pi r

⇒ r = \frac{4}{2\pi}

⇒ r = \bf \frac{2}{\pi}

• Now we can calculate the height using the formula for volume of a cylinder:

\mathrm{Volume} = \boxed{\pi r^2 h}

Solving for h :

⇒ 36 = \pi \cdot (\frac{2}{\pi}) ^2 \cdot h

⇒ h = \frac{36 \pi^2}{4 \pi}

⇒ h = 9 \pi

⇒ h = \bf 28.3 \space\ m

A 90-day simple interest loan in the amount of $2350 will be paid in full in the amount of $2500 . Find the rate of the loan.
ivolga24 [154]

Answer:

The rate of simple interest is 25.89 %  

Step-by-step explanation:

Given as :

The principal = $2350

The Amount = $2500

The time period = 90 days = \frac{90}{365} year = 0.2465 year

Let The rate of interest = R %

So, Interest = Amount - Principal

Or, Interest = $2500 - $2350 = $150

<u>From Simple Interest method </u>

Simple Interest = \frac{Principal\times rate\times Time}{100}

Or, $150 =  \frac{$2350\times rate\times 0.2465 }{100}

or, $150 × 100 = $579.275  × Rate

So, Rate = \frac{15000}{579.275}

∴    Rate = 25.89 %

Hence The rate of simple interest is 25.89 %    Answer
