Bree made three identical birthday hats out of construction paper. Each was in the shape of a cone. The diameter of each hat was

6.6 inches and the slant height was 8.4 inches. How many square inches of construction paper did Bree need to make the three hats? Use 3.14 for Pi and round your answer to the nearest hundredth. (Recall the formula L A = pi r l) 87.04 in2 174.08 in2 261.12 in2 522.24 in2

Answer:

(C)261.12 Square Inches

Step-by-step explanation:

The diameter of the Cone Hat = 6.6 inches

Radius = Diameter/2=6.6/2=3.3 Inches

The slant height = 8.4 inches.

To determine how many square inches of construction paper did Bree need to make the three hats, we find the Curved Surface Area of the Cones.

Curved Surface Area of a Cone =\pi r l

Therefore, the area of paper used for the 3 hats

=3 X Area of One Hat

=3 \times \pi r l\\=3 \times 3.14\times 3.3 \times 8.4\\=261.12$ Square Inches

Answer:

A

Step-by-step explanation:

To sovle this we must combine the numbers togther and the variables togther.

We have:

8c+6-3c-2

Lets take out the c's and combine them:

8c -3c

=

5c

Now lets take out the numbers:

6-2

=

4

Now lets put these back together and we get the expression:

5c+4

This looks like A.

Hope this helps! :D

You deposit $300 in a savings account that pays 6% interest compounded semiannually. How much will you have at the middle of the
Otrada [13]

Answer:

Please check the explanation.

Step-by-step explanation:

a)  How much will you have at the middle of the first year?

Principle P = $300

Annual rate r = 6% = 0.06 per year

Compound n = Semi-Annually = 2

Time (t in years) = 0.5 years

Total amount = A = ?

Using the formula

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

substituting the values

A=300\left(1+\frac{0.06}{2}\right)^{\left(2\right)\left(0.5\right)}

A=300\cdot \frac{2.06}{2}

A=\frac{618}{2}

A=309 $

Therefore, the total amount accrued, principal plus interest,  from compound interest on an original principal of  $ 300.00 at a rate of 6% per year  compounded 2 times per year  over 0.5 years is $ 309.00.

Part b) How much at the end of one year?

Principle P = $300

Annual rate r = 6% = 0.06 per year

Compound n = Semi-Annually = 2

Time (t in years) = 1 years

Total amount = A = ?

Using the formula

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

so substituting the values

A\:=\:300\left(1+\frac{0.06}{2}\right)^{\left(2\right)\left(1\right)}

A=300\cdot \frac{2.06^2}{2^2}

A=318.27 $

Therefore, the total amount accrued, principal plus interest,  from compound interest on an original principal of  $ 300.00 at a rate of 6% per year  compounded 2 times per year  over 1 year is $ 318.27.
