Question 4:

OOOOOHHH a breakthrough! I was confused when I read this question but now I get it!

Okay when dividing this equation I would do this

5^4

Since 25 is 5 x 5 I would mark it as 5^2, and then I can subtract!

5^4

5^2 =

5^2

If you do it like this then it would be the first choice.

What is the volume of a hemisphere with a radius of 2.3m round to the nearest tenth of a cubic meter

kodGreya [7K]

Answer: $25.5 m^{3}$

Step-by-step explanation:

If the volume of a sphere is

$V=\frac{4}{3} \pi r^{3}$

Where $r=2.3 m$ is the radius

The volume of a hemisphere is half the volume of the total sphere:

$V_{hemisphere}=\frac{V}{2}=\frac{\frac{4}{3} \pi r^{3}}{2}$

$V_{hemisphere}=\frac{2}{3} \pi r^{3}$

Solving this equation:

$V_{hemisphere}=\frac{2}{3} \pi (2.3 m)^{3}$

Finally:

$V_{hemisphere}=25.48m^{3} \approx 25.5 m^{3}$

Answer expression 1:<br><br> 6 x 7 - 3^2 x 9 + 4^3

skad [1K]

In order to get the answer to this question you will have to use PEMDAS and solve.

$6\times7-3^2\times9+4^3$

Using PEMDAS:

$3^2=3\times3=9$

$4^3=4\times4\times4=64$

$6\times7-9\times9+64$

$6\times7=42$

$9\times9=81$

$42-81+64$

$81+64=145$

$42-145$

$42-145=-103$

$=-103$

Therefore your answer is "-103."

Hope this helps.
