The circumference is 2pi*r=5.,38
 ⇒ r= 53.38/pi=53.38/3.14= 17

The area is pi*r^2= 3.14*17^2=907.46

A=907.46

using the formula c squared equals a squared plus b squared what is the length of side C, if B equals 20and A equals 15
Dennis_Churaev [7]
C^2 = A^2 + B^2
C^2 = 15^2 + 20^2
C^2 = 225 + 400
C^2 = 625
C = √(625)
C = 25

How is an equation like an expression? How is it different?
morpeh [17]

Answer:

See explanation.

Step-by-step explanation:

An expression is a <u>set of terms that are combined using addition, subtraction, multiplication, or division.</u> The following are examples of expressions:

2x-1

5y+8

2

Note: expressions do not equal anything.

In contrast, equations are <u>expressions that equal at least one term.</u> The following are examples of equations:

2y-4=26

4x-4=0

x=10

y=x+2

Note: equations <u>do</u> equal a term, as shown in the examples.
