celia filled the glasses shown below completely with water. the total amount of water that celia poured into the glasses is 80 cubic centimeters. what is the height of glass 1? round your answer to the nearest tenth. (use π = 3.14.) note that all measurements are in centimeters and images are not drawn to scale.

The height of glass 1 is 7.6 cm.

Step-by-step explanation:

We can see that glass 1 is a cylinder whose volume is given by :

its r =

h = ?

The second glass is a cone with h = 6.3 and r =

Volume is given as :

=>

V = 26.38 cubic cm

Given is :

The total amount of water that Celia poured into the glasses is 80 cubic centimeters.

This means she poured cubic cm of water in cylindrical glass. Solving for 'h'

h = 7.6 cm

Therefore, the height of glass 1 is 7.6 cm.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

answer for #1 is c

answer for #2 is d
