The surface area of a cone is 54 square inches. What is the surface area of a similar cone that is three times as large?

12345 [234]

<u>Given</u>:

Given that the surface area of the cone is 54 square inches.

We need to determine the surface area of the cone that is similar to the cone three times large.

<u>Surface area of the similar cone:</u>

Let us determine the surface area of the similar cone.

The surface area of the similar cone can be determined by multiplying the surface area of the cone by 3. Because it is given that the similar cone is three times large.

Thus, we have;

$SA = 3 \times 54$

$SA=162$

Thus, the surface area of the similar cone is 162 square inches.

Write an equation of a line that is parallel to y = 3x – 5 and goes through the point (3, 1).

scoray [572]

Paralell means has same lsope
y=mx+b
m=slope

given
y=3x-5
slope=3

y=3x+b
find b
(3,1)
x=3
y=1
sub and find b

1=3(3)+b
1=9+b
minus 9 both sides
-8=b

y=3x-8 is equation

zvonat [6]

Answer:

4 hours of rental

Step-by-step explanation:

y1 = 20 + 13.5x

y2 = 6 + 17x

20 + 13.5x = 6 + 17x

20 - 6 = 17x - 13.5x

14 = 3.5x

x = 4

Costs y1 and y2 are equal on renting for 4 hours
