Answer:

Step-by-step explanation:

Circumference pf base of cone = 24 inches

2πr = 24

r=\frac{24}{2\pi}\\\\r=\frac{12}{\pi}

Lateral surface area = πrl

=\pi *\frac{12}{\pi }*20\\\\=12*20\\

= 240 square inches

EEF has vertices D(1, 3), E(2, -4), and F(-3, 1). What are the vertices T<4, 1> (DEF).
Triss [41]

The vertices T<4, 1> (DEF) are D' = (5, 4), E' = (6, -3) and F' = (1, 2)

<h3>How to determine the vertices?</h3>

The vertices of the triangle are given as:

D(1, 3), E(2, -4), and F(-3, 1).

The transformation represented by T<4, 1> (DEF) is:

(x,y) = (x + 4, y + 1)

So, we have;

D' = (1 + 4, 3 + 1)

D' = (5, 4)

E' = (2 + 4, -4 + 1)

E' = (6, -3)

F' = (-3 + 4, 1 + 1)

F' = (1, 2)

Hence, the vertices T<4, 1> (DEF) are D' = (5, 4), E' = (6, -3) and F' = (1, 2)
