Circumference of a circle: 2 * Pi * R
1. Calculate radius from diameter.
Radius = Diameter/2
Radius = 15/2
Radius = 7.5cm
Formula to calculate the circumference:
2 * Pi * R
= 2 * Pi * 7.5
= 15 * Pi
= About 47.10 cm in terms of Pi.
So, in conclusion, the circumference if this circle is about: 47.10cm.
Answer:
Year 2034
Step-by-step explanation:
In 2000, 64% had one or more pets
<em>Since decreasing at 1% per year, we can say:</em>
<em>In 2001, 63%</em>
<em>In 2002, 62%</em>
<em>In 2003, 61%</em>
<em>In 2004, 60%</em>
<em>And so on</em>
<em />
To go to 30% from 60% in 2004, we would need to decrease 60 - 30 = 30%, and that will occur after 30 more years. So that would be the year
2004 + 30 = 2034
So, year 2034
Answer:
1. 0.8 cm
2. 1.6 cm
Step-by-step explanation:
1.
The scale for 2nd map is 1 cm to 50 km, that means "1 cm on map" is "50 km in real life".
We already know distance from Cleveland to Cincinnati is 40 km, which is less than 50, so we know the distance on map would be less than 1 cm.
So we set up ratio and figure out (let x be distance on map from Cleveland to Cincinnati):
Hene, 0.8 centimeters would be the distance in 2nd map
2.
A scale of 1:50 means 1 cm equal 50 cm
So, 0.8m would be
0.8 * 100 = 80 cm
Hence, 80 cm would be represented by 80/50 on the map, that is:
That is 1.6 centimeters
Answer:
x= 11/5 OR 2.2
Step-by-step explanation:
Answer: Yes
Step-by-step explanation: A triangle can be formed because A+B>C
A and B are 2.9 and 4.8
Since those numbers have the least value
I added both and found that A and B are equal to 7.7
7.7>7.4
These sides could form a triangle
