Find the lateral and surface area of each cone

Sophie [7]

Answer:

$\large\boxed{L.A.=153\pi\ mm^2}\\\boxed{S.A.234\pi\ mm^2}$

Step-by-step explanation:

The formula of a lateral area of a cone:

$L.A.=\pi rl$

r - radius

l - slant height

The formula of a surface area of a cone:

$S.A.=\pi r^2+\pi rl$

We have r= 9mm and l = 17mm. Substitute:

$L.A.=\pi(9)(17)=153\pi\ mm^2$

$S.A.=\pi(9^2)+153\pi=81\pi+153\pi=234\pi\ mm^2$

Translate the word into a equation 15 is equal to 9 more than a number

WITCHER [35]

Answer:

Step-by-step explanation:

We'll go part by part.

"15 is equal to" so simple enough 15= now what is it equal to?

9 more than a number. Well what does that mean? it might help if we try out an actual number. What is 9 more than 3? 12, so another way of writing that is +9. It's not telling us the number we are adding 9 to so it's a variable. So we'll say x + 9.

This leaves us with 15 = x + 9, which you could even solve.
