the answer is D
Answer:
The answer is 50.24 inches
Step-by-step explanation:
Look a the diameter. Diameter is twice the radius. The formula for area is A=πr2. Divide 8 by 2. Multiply them like this: 3.14(4in.)(4in.). This is because you have to do the radius twice, hence the formula. This makes the answer 50.24 inches in area.
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: There are 35 large and 25 small packages on the truck .
Step-by-step explanation:
Let x = Number of large packages.
y= Number of small packages.
According to the given question, we have the following system of equations:-
Substitute the value of x from (2) in (1) , we will get
Put value of y in (2) , we get
Hence, there are 35 large and 25 small packages on the truck .
