What is the volume of this cone? Use 3.14 for π and round your answer to the nearest tenth.
photoshop1234 [79]

Answer:

volume = 33.5 in³

Step-by-step explanation:

<u>Formula</u>:

\sf volume \ of \ a \ cone=\dfrac13\pi r^2h

<u>Given</u>:

  • r = 2 in
  • h = 8 in
  • π = 3.14

Substituting the given values into the formula:

\sf \implies volume=\dfrac13 \times 3.14 \times 2^2 \times 8

                  =\dfrac13 \times 3.14 \times 4 \times 8

                  \sf =33.49333333...

                  \sf =33.5 \ in^3 \ (nearest \ tenth)

Answer:

$8.96

Add $1.49 to $7.47

(1.49+7.47=8.96)

Each month Liz pays $35 to her phone company just to use the phone. Each text she sends costs her an additional $0.05. In March
olchik [2.2K]
First let's set up an equation: 35+0.05t. 
35 is the phone rate per month plus the number of texts (t) times 0.05 (cost of 1 text)

Now we can find the amount of texts she sent each month.

March
 35+0.05t=72.60
-35               -35
0.05t=37.60
------   -------
0.05    0.05
t=752

April
 35+0.05t=65.85
-35            -35
0.05t=30.85
------   -------
0.05    0.05
t=617

She sent 752 texts in March and 617 texts in April.
