  • Circumference = 4 cm
  • Let the radius be r.
  • Therefore, 2πr = 4 cm
  • Given, height = 9 cm.
  • Therefore, curved surface area of the cylinder = 2πrh
  • = (4 × 9) cm^2
  • = 36 cm^2

<u>Answer:</u>

<u>Answer:36 cm^2</u>

Hope you could understand.

Suppose KLMN ~ PQRS. Find the value of x.
arlik [135]

Complete question is attached.

Answer:

B) 8

Step-by-step explanation:

In this question, KLMN ~ PQRS. This means they are similar shapes.

From the image, we could denote that:

KL ~ PQ

LM ~ QR

Given that:

KL = 12

PQ = 30

QR = 20

LM = x

To find x, let's use tge expression:

\frac{KL}{PQ} = \frac{LM}{QR}

=  \frac{12}{30} = \frac{x}{20}

Cross multiplying, we have:

12 * 20 = 30x

240 = 30x

To find x, let's divide both sides by 30.

\frac{240}{30} = \frac{30x}{30}

8 = x

x = 8

The correct option is option B.

PLEASE ANSWER QUICKLY WITH DESCRIPTION ON HOW TO DO IT!!! If (-a^2b3)(2ab^2)(-3b)=ka^mb^n what is the value of m+n????
iragen [17]

Answer:

m+n=9

Step-by-step explanation:

Put the equation into the form ka^mb^n by multiplying the coefficients (-1*2*-3), so k= 6, then add the exponents of a together, a^2+a^1= a^3, m=3.

Now you have 6a^3, next we do the exponents of b together, b^3, b^2, b^1= b^6, n=6.

This is 6a^3b^6. m=3 and b=6, so add m+n=9.
