So basically you just need to do the Pythagorean theorem to find the sides of the shaded rectangle, with c being the length of the side.

Small side:
2^2 + 6^2 = c^2
4 + 36 = c^2
40 = c^2
C is similar to 6.32456

Long side:
12^2 + 4^2 = c^2
144 + 16 = c^2
160=c^2
C is similar to 12.64911

And then you just multiply!

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

In the coordinate plane, three vertices of rectangle HDK are H(0, 0), (0, d), and Kle, 0). What are the coordinates of point J?

Alik [6]

<u>Answer:</u>

K = (e, d)

<u>Step-by-step explanation:</u>

We are given the coordinates of three vertices of a rectangle and we are to find the coordinates of the fourth point J.

H (0, 0)

I (0, d)

K (e, 0)

J = ?

We can find this using the following formula:

K = H + (I - H) + (K - H)

K = H + I - H + K - H

K = I + K - H

Substituting the given values in it to get:

K = $(0, d) + (e, 0) - (0, 0)$

K = $(0+e-0, d+0-0)$

K = (e, d)
