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:

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

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

Find an equation for the line with the given properties. Express the equation in? slope-intercept form. Slope? = 6 ?; containing

Firlakuza [10]

Answer:

y=6x+7

Step-by-step explanation:

We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point given and a slope from the equation. We will chose point-slope since we have a point and can find the slope.

Point slope: $y-y_1=m(x-x_1)$

We will substitute $m=6$ and $x_1=-1\\y_1=1$ .

$y-1=6 (x-(-1))$

We can simplify and convert to slope intercept form.

$y-1=6 (x-(-1))\\y-1=6(x+1)\\y-1=6x+6\\y=6x+6+1\\y=6x+7$
