Is 105/2 equivalent to 210/4

jarptica [38.1K]

Yes.

$\dfrac{210}{4}=\dfrac{105\cdot\not2}{2\cdot \not2}=\dfrac{105}{2}$

each evening, Marisol spend at least twice as much time reading as she spends doing homework. If Marisol works on her homework f

erica [24]

To get the result we can use knowledge that reading is 2 times longer than HW.
To find this value we just have to multiply 42 times 2 so
40*2=80
Its 1 hour and 20 min - its the result

What is the volume of a hemisphere with a diameter of 47.5 m, rounded to the nearest tenth of a cubic meter?

Lunna [17]

Answer:

28043.3 $m^{3}$

Step-by-step explanation:

Formula for volume of a hemisphere can be termed as:

$V = \dfrac{2}{3} \pi r^{3}$

where $r$ is the radius of hemisphere

Please refer to the figure attached for the sample figure of a hemisphere.

We are given here, diameter of hemisphere = 47.5 m

Relation between diameter and radius is given as :

$r = \dfrac{d}{2}$

where, $r$ is the radius and

$d$ is the diameter.

So, $r = \dfrac{47.5}{2}\ m$

Volume is:

$V = \dfrac{2}{3} \pi (\dfrac{47.5}{2})^3\\\Rightarrow \dfrac{2}{3} \times 3.14 \times (\dfrac{47.5}{2})^3\\\Rightarrow 28043.3\ m^3$

Hence, volume of given hemisphere is 28043.3 $m^{3}$ .
