A Circle Has A Circumference Of 8. It Has An Arc Of Length 32/5.What Is The Central Angle Of The Arc,

Answers

Answer 1

Answer:

288°

Step-by-step explanation:

[tex]l = \frac{ \theta}{360 \degree} \times c \\ \\ where \\ l = length \: of \: the \: arc \\ \theta \: = measure \: of \: the \: central \: angle \\ c = circumference \: of \: the \: circle \\ \\ \implies \: \frac{32}{5} = \frac{ \theta}{360 \degree} \times 8 \\ \\ 40 \theta = 32 \times 360 \degree \\ \\ \theta = \frac{ 32 \times 360 \degree}{40} \\ \\ \theta =32 \times 9 \degree\\ \\ \theta =288 \degree [/tex]

Answer:

100 π

Explanation:

Since the equation for the area of a circle is π r^2, and the diameter is 20m. There is enough info to proceed.

First, half the 20m to 10m since the radius is 1/2 of the diameter.

Next, plug this into the formula to get the answer:

π 10^2

π 100

100 π is the answer, since it is looking for it in terms of π.

Convenience sampling.

Step-by-step explanation:

Convenience sampling can be understood as a type of sampling that occurs when there is high availability of the population to be investigated.

This method incurs several criticisms because it is not a sampling method that reflects the reality of a population, but convenience sampling can be advantageous due to the speed with which the data are collected and the research initiated, thus being a method recommended for pilot tests.

Answers

Answer:

(-3,-1)

Step-by-step explanation:

So we need to find a number, x=a, such that when we average that number and x=3, we get x=0.

Since we want x=0 to be middle and x=3 is 3 units right of 0, then we are looking for number 3 units left of 0 which is x= -3.

Since we want y=2 to be the middle and y=5 is 3 units above 2, then we are looking for a number 3 units below 2 which is y=-1.

The other endpoint is (-3,-1).

Let's average (-3,-1) and (3,5).

(-3+3)/2=0/2=0

(-1+5)/2=4/2=2.

Given that a = 14 cm and b = 25 cm, work out the area of the triangle.

Answers

you haven't attached a picture, so i'll take b= 25 cm and h= 14 cm
area of triangle= 1/2*bh
=1/2*350
= 175 sq. cm.

Answer:

175

Step-by-step explanation:

I am assuming that you mean that a and b are both bases of a  right triangle. Please correct me if I am wrong.

14 * 25/2 = 350/2 = 175

The area would then be 175 cm²

Answers

Answer:

4/9

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.

Probability the number is less than 10 = total numbers less than 10 / sum of numbers
