Answer:

18.84

Step-by-step explanation:

Since the formula for circumference is $C=2\pi r$ , we need to first find the radius. The formula for the radius is $r=\frac{\sqrt{A\pi } }{\pi }$ , so we will get $r=3$ . Substitute that into $C=2\pi r$ , and we get $C=18.84$ . Hope this helps!

A plant measures 0.5 in. at the end of Week 1 and 14 in. at the end of Week 5. find the rate of change

CaHeK987 [17]

The change in growth was 14 - 0.5 = 13.5 inches.
Since it is over the course of 5 weeks, divide 13.5 by 5.
13.5/5 = 2.7
2.7 = 270%

The rate of change was 270%. Hope this helps!

A sandwich costs 5:70 and a piece of fruit costs 2:15 if you have a 20 bill, how much change will you get ?

Gelneren [198K]

Well if you buy only 1 of each, it would cost you 7.85 in total. if you subtract that from 20, it equals 12.15.
you can also make it a linear equation if you want more or less than 1 fruit and or sandwich
s=sandwich
f=fruit
5.7f+2.15f=20

Part 1: Use the information provided to write the standard form equation of each circle. Please show the work.

dusya [7]

Answer:

1. (x + 2)² + (y - 9)² = 64

2. (x + 6)² + (y - 9/2)² = 100

3. (x - 15)² + (y + 10)² = 1

Step-by-step explanation:

Equation of a circle:

(x - h)² + (y - k)² = r²

1. Center: (-2, 9), Radius: 8
