Answer:

Therefore,

$C=\pi d\\C\approx 3.14 \times d\\C\approx 43.96\ inches$

Step-by-step explanation:

Let Assume Some Diameter of a Circle, to Solve it

Diameter = d = 14 inch ( say )

C =Circumference

Pi =constant = 3.14

To Find:

C = ?

Solution:

Formula for Circumference of a Circle is given as

$C=\pi d$

Where,

C = Circumference

d = Diameter

Now Substitute d = 14 inches we get

$C=3.14\times 14\approx 43.96\ inches$

This way we can find the circumference for any 'd' i.e Diameter

Therefore,

$C\approx 43.96\ inches$

To find the area of a triangle, you can use the expression b × h ÷ 2, where b is the base of the triangle and h is its height. W

Zolol [24]

Answer:

Step-by-step explanation:

b x h is finding a square or rectangle, but since a triangle is half of a rectangle or square you can divide that by 2. So, 8 (b) x 4 (h) = 32, 32 / 2 = 16. Hope this helps! :D

Write an expression to represent the perimeter of:

kotykmax [81]

"Perimeter" is the distance all the way around the drawing. If the drawing has sides, then the perimeter is the SUM of the lengths of all the sides. It's exactly the distance an ant would have to walk along the line, to get all the way around to where he started from.

To get the perimeter of the triangle, you have to add up the lengths of the three sides.

(2a - 3) + (2a) + (3a + 1) =

2a - 3 + 2a + 3a + 1 .

Add up all the 'a's: 2a + 2a + 3a = 7a

Add up all the just plain numbers: -3 + 1 = -2

Write them together, as a binomial: 7a - 2

THAT's your expression for the perimeter.

2. Lamar purchases comic books at garage

Otrada [13]

Answer:

Lamar will charge $\$7$ to the comic dealer for a comic book.

Solution:

It is given that lamar purchases a comic book for $\$4$ . He then marks up the price of a comic book by $75\%$ which means he increases the price of the book by $75\%$ and then sells it to the comic dealer.

We have to find out how much will he charge the comic book dealer.

New price of the book after lamar marks up the price is given by

New price $= \$4 + \frac{75}{100} \times \$4$

= $\$4 + \$3$ $= \$7$

Thus, lamar will charge $\$7$ to the comic dealer for a comic book.
