kirza4 [7]2 years ago
7 0

Answer:

Step-by-step explanation:

y = 3x - 5

6x + 3y = 15

Substitute the first equation into the second

6x + 3(3x - 5) = 15

6x + 9x - 15 = 15

15x = 30

x = 2

Then use the answer in the first equation and solve

y = 3(2) - 5

y = 6 - 5

y = 1

A cylinder has a volume of 288 pi cubic meters and a height of 9 meters. What is the area of the base?
Pavlova-9 [17]

Answer:

The area of the base is about 32 square meters

Step-by-step explanation:

V = pi times r^2 times h which is the formula.

Since the volume is 288, and the height is 9 it is,

288 = pi times r^2 times 9,

288/9 = pi times r^2 times 9/9

32/pi = pi/pi times r^2

10.2 = r^2

The square root of 10.2 is about 3.19

Area formula is pi times radius, r^2

3.19 times 3.19  or 3.19^2 = 10.1761

10.1761 times pi is 31.96 which is about 32 square meters.

I hope this helps!
