Answer:

407 mm²

Step-by-step explanation:

The formula for the surface area of a clyinder is: A = 2\pir · (r + h)

Plugging in the given values, we have: A = 2\pi4 · (4 + 12.2)

A = 2\pi4 · (4 + 12.2)

A = 2\pi4 · 16.2

A = 2(3.14)4 · 16.2

A = 406.944

A = 407 (rounded)

hope this helps!

If f(x) = 4x + 15, then f(-3) = ?
WARRIOR [948]

Answer:

\Huge \boxed{3}

Step-by-step explanation:

The function is given :

f(x) = 4x + 15

For f(-3), the input for the function f(x) is -3.

Replace the x variable with -3.

f(-3) = 4(-3) + 15

Evaluate.

f(-3) = -12 + 15

f(-3) = 3

The output for f(-3) is 3.

So your parent hasn't joined you on the Brainly express to Achievement-ville. We'll get them on board. Parents are busy people, but you can be the boss and remind them. Remind them how Brainly boosts you with expert knowledge. Remind them that tons of students already get grade upgrades with Brainly Plus. Remind your parent of the power they have to raise you to your full potential. We think they would agree. You deserve every education advantage.

Need help on this equation its on the paperclip
s344n2d4d5 [400]

Answer:

Blank 1: 1 Blank 2: 8 Blank 3: 72

Step-by-step explanation:

What it is basically saying is that 9*8 is equal to 10*8 - 1*8 [Blank 1]. 10 times any number is a friendly number, it all ends with a 0. The question is saying that it is easier to think of a friendly number and subtracting from that. 10 eights - 9 eights is equal to 1 eight. So we take away 1*8=8 from 10*8=80, or in other words, 80-8 [Blank 2]= 9*8=72 [Blank 3].

Are you starting to see what I mean?
