The formula of a volume is V = l*w*h
The prism is 4 cm long, 1.4 cm wide, and 3 cm tall.
4 * 1.4 * 3 = 16.8
The volume is 16.8 cubic cm.
Answer:
T = 96
Step-by-step explanation:
From the question given above, we were told that the time, T (seconds) it takes for a pot of water to boil is inversely proportional to the cooker setting, H. This can be written as:
T ∝ 1/H
T = K/H
Cross multiply
K = TH
Next, we shall determine the value of K. This can be obtained as follow:
H = 8
T = 120
K =?
K = TH
K = 120 × 8
K = 960
Finally, we shall determine the value of T when H = 10. This can be obtained as illustrated below:
H = 10
K = 960
T =.?
T = K/H
T = 960/10
T = 96
Answer:
Step-by-step explanation:
Lets assume that a sphere with greater radius = R = 5cm
And a sphere with smaller radius = r = 4cm
Volume of a sphere = 4/3 π * r³
To find the volume of a sphere with radius 5.
Put the value in the formula.
=4/3π * r³
=4/3π *(5)³
5³ = 5*5*5=125
=4/3π * 125
=4/3 *3.14 *125
=1570/3
=523.3 cm³
Now find the volume of sphere with radius= 4
4/3π*r³
=4/3π * 4³
4³= 4*4*4=64
=4/3*3.14*64
=803.84/3
=267.9cm³
Now to find the space between the spheres subtract the volume of smaller sphere from the volume of larger sphere.
We can write it as:
Space between the spheres = Volume of larger sphere - Volume of smaller sphere
= 523.3 cm³ - 267.9cm³
= 255.4cm³ ....
Answer:
Your answer is 46 minutes.
Step-by-step explanation: By doing the median of the numbers you order the pairs from least to greatest. 38, 45, 47, 52. You find the middle number if its an even number of pairs you pick the two middle most numbers and add them together.
45 + 47= 92
Then you divide the sum by the number of pairs. Which we have 2 pairs.
92/2 = 46 hence your answer will be 46 minutes.
Answer:
90 degrees
Step-by-step explanation:
BCO = 66
The whole ABC is 180
So BCO and BDO = 90
Therefore BAO must = 90 degrees
