Vinvika [58]

Answer: y=-4x+2

Why: Find slope— 2-14/0+3 = -12/3 = -4

First put it in slope point form
y-2=-4(x-0)

Simplify
y-2=-4x

So...
y=-4x+2

The area of the base of the cone is 64π square millimeters, and the area of the lateral surface is 112π square millimeters. Find

baherus [9]

Answer:

Radius = 8 mm

Slant Height = 14 mm

Step-by-step explanation:

Base of a cone is a circle.

Area of circle is given as $A=\pi r^{2}$

Where $r$ is the radius.

Given that

$A = 64 \pi\ mm^2\\\Rightarrow \pi r^{2} = 64\pi \\\Rightarrow r^{2} = 64\\\Rightarrow r = 8\ mm$

Hence, radius is 8 mm.

Formula for Lateral Surface Area of a cone:

$LSA = \pi rl$

Where $r$ is the radius and

$l$ is the slant height of cone

Given that $LSA = 112 \pi\ mm^2$

$\Rightarrow 112\pi = \pi \times 8 \times l\\\Rightarrow 8 \times l = 112\\\Rightarrow l = 14\ mm$

Hence, slant height is 14 mm
