<h3>Solution:</h3>

Radius = Diameter ÷ 2 = 13 ÷ 2 = 6.5 cm

Circumference = 2πr

→ Circumference = 2 × π × 6.5

→ Circumference = 13 π cm

Therefore, circumference of given circle = <u>13 π cm</u>

<em>Hope</em><em> it</em><em> helps</em><em> </em><em>you </em><em> </em>:)

What is another way to write this number?<br><br> 300 + 70 + 5 + 8<br> 300 + 70 +<br> 10<br> 100
ololo11 [35]

Answer:

Combine the terms

300 + 70 = 370

5/10 + 8/100

Note that first, you must find common denominators. What you multiply to the denominator, you multiply to the numerator. Multiply 10 to the numerator and denominator of 5/10

(5/10)(10/10) = 50/100

50/100 + 8/100

Combine the terms

50/100 + 8/100 = 58/100

370 58/100 is another way to write it

Find the inverse f(x)=6x+7
Lorico [155]

Answer:

f^{-1} (x) = \frac{x-7}{6}

Step-by-step explanation:

let y = f(x) , then rearrange making x the subject

y = 6x + 7 ( subtract 7 from both sides )

y - 7 = 6x ( divide both sides by 6 )

\frac{y-7}{6} = x

Change y back into terms of x with x = f^{-1} (x) , then

f^{-1} (x) = \frac{x-7}{6}
