Answer:
1: r = 2.4 cm
2: V = 57.8765 cm^3
Step-by-step explanation:
1:
The volume of a sphere is given by V = (4/3) * pi * (r^3), being 'r' its radius.
So if the volume is 463.01 cm^3, we have that:
463.01 = (4/3) * pi * (r^3)
463.01 * 3 = 4 * 3.14 * r^3
r^3 = 463.01 * 3 / (4 * 3.14) = 110.59156
r = 4.8 cm
2:
The radius of the second sphere is 4.8/2 = 2.4 cm, so its volume is:
V = (4/3) * 3.14 * (2.4^3) = 57.8765 cm^3
Well the order is pemdas
parenthasees, exponents, mutiplication or divistion whicher comes first left to right, then addtion and subtract whicherver comes first from left to right
so fractions are technically division, so just first simplify them, then do whaterver you want exg
1/2 times 4/8
first simpligy
1/2 times 1/2
multiply
1/2 times 1/2=1/4
To solve this problem you must follow the proccedure shown below:
1. You have that <span>the pasture must contain 128 square meters and no fencing is required along the river. Then:
A=LxW
A is the area
L is the lenght
W is the width
2. Let's clear W:
W=A/L
W=128/L
3. The formula of the perimeter is:
P=2L+W
P=2L+(128/L)
4. Now, you must derivate:
dP/dL=0
2+(128/L</span>²)=0
<span> L=8 meters
W=A/L
W=128/8
W=16 meters
</span>
A negative correlation: when the number of years increase the value of the car decrease.
