The perimeter of the semicircle is 19π cm if the diameter of the circle is 38 cm.

<h3>What is a circle?</h3>

It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)

We have a circle with diameter of 38 cm.

Diameter = 38 cm

The radius of the circle = 38/2 = 19 cm

Perimeter of the circle = 2πr = 2π(19) = 38π cm

Perimeter of the semicircle = 38π/2 = 19π cm

Thus, the perimeter of the semicircle is 19π cm if the diameter of the circle is 38 cm.

zepelin [54]

Answer:

No, she needs 1/6 cup more

Step-by-step explanation:

She has 3 1/4 cups

She uses 2 2/3

Subtract

3 1/4 - 2 2/3

Get a common denominator of 12

3 1/4 *3/3 - 2 2/3 *4/4

3 3/12 - 2 8/12

Borrow 1

2 12/12 +3/12 - 2 8/12

2 15/12 - 2 8/12

7/12

She borrows 1 cup

1 7/12

She needs 1 3/4 *3/3 =1 9/12

She is short

1 9/12 - 1 7/12 = 2/12 or 1 /6

# 15. Q. Find the area of the trapezoid

harina [27]

Answer:
219.96 yd²

Explanation:
The area of the trapezoid can be calculated using the following rule:
Area of trapezoid = $\frac{b1 + b2}{2} * h$
where:
b1 is the length of the first base
b2 is the length of the second base
h is the height

Now, in the given we have:
b1 = 15.8 yd
b2 = 21.8 yd
h = 11.7 yd

Substitute with the givens in the above equation to get the area as follows:
area = $\frac{15.8 + 21.8}{2} * 11.7 = 219.96 yd^2$

Hope this helps :)

Looking at the repayment time of peer to peer users how would you assume it compares to that every payment via cash or check? wh

Rina8888 [55]

Peer-to-peer is good for fast payment but is lacking in the transfer of funds security as there is mostly made b/w people with one unknown history or background, most people meeting for the first time, Compared to cash or check which is handled physically. This is further explained below.

<h3>Looking at the repayment time of peer-to-peer users how would you assume it compares to that every payment via cash or check?</h3>

Generally, P2P, which stands for peer-to-peer, is a method of payment that enables users to make purchases without needing to have access to their financial institution's account information. The transfer is completed quickly and, in most cases, at no cost. There is a generational divide in terms of adoption, but the vast majority of Americans today make use of mobile payment applications.

In conclusion, Peer-to-peer transactions are typically conducted between people who do not know each other's histories or backgrounds, and the majority of transactions involve people who are meeting for the first time. This makes peer-to-peer transactions less secure than cash or checks, which are physically handled. Peer-to-peer transactions are useful for making payments quickly.
