A cylinder with radius 3 feet and height 5 feet is shown.
Leviafan [203]

Answer:

The volume of the cylinder is <u>141.23 cubic feet </u>

Step by step explanation :

<u>Given</u>-

  • Radius of cylinder = 3 feet
  • Height of cylinder = 5 feet

Now, we know that

<h3>\boxed {\mathfrak \red{ volume \: of \: cylinder = \pi {r}^{2} h}}</h3>

where, r is the radius of the cylinder & h is the height of the cylinder.

Now,

Volume of the cylinder = \frac{22}{7}  \times  {3}^{2}  \times 5

=  \frac{22}{7}  \times 3 \times 3 \times 5

<h3>=   \frac{990}{7}</h3>

= 141.428571 ( approximately )

=  \boxed{ 141.43 \:  \mathfrak { {ft}^{3}} }

What is the total amount in an investment of $3500 that was compounded quarterly for 8 years at a rate of 5%?
erica [24]

Answer:

Principal = 3500

Time = 8 years

We are given that compound quarterly

So, No. of compounds per year = 2

Rate of interest = 5%

Formula : A=P(1+\frac{r}{n})^{nt}

Substitute the values :

A=3500(1+\frac{0.05}{2})^{2 \times 2}

A=3863.345

Interest = 3863.345 - 3500 = 363.345

Hence the total amount in an investment of $3500 that was compounded quarterly for 8 years at a rate of 5% is $3863.345 and the interest that was made on that account mentioned is $363.345

A ribbon is 30cm long and it is cut into three pieces such that each piece is 2cm longer than the next. Represent this as an equ
Alisiya [41]

Answer:

Step-by-step explanation:

3 pieces such that each piece is 2 cm longer then the next...

x , x + 2, x + 4

x + x + 2 + x + 4 = 30

3x + 6 = 30

3x = 30 - 6

3x = 24

x = 24/3

x = 8

x + 2 = 8 + 2 = 10

x + 4 = 8 + 4 = 12

check...

8 + 10 + 12 = 30

18 + 12 = 30

30 = 30 (correct)...it checks out

the ribbon lengths are : 8 cm, 10 cm, and 12 cm
