Answer:
The volume of the solid will be = 134.1 cubic units.
Step-by-step explanation:
The base of a solid has the equation of a circle x² + y² = 16 in the xy-plane. Cross-sections perpendicular to the y-axis of the solid are semicircles.
Therefore, the solid will be the shape of a hemisphere.
Now, the radius of the hemisphere will be 4 units.
{Since the base of the hemisphere is on the xy-plane and have equation
x² + y² = 4²}
Therefore, the volume of the solid will be =
cubic units. (Answer)
Answer:
Step-by-step explanation:
To find it we will divide the miles from hours
= 110 ÷ 2 = 55
165 ÷ 3 = 55
220 ÷ 4 = 55
The answer is 55
Percent decrease is really interesting
Let us solve this quickly.
80-17=63
63/80 = 0.7875
Percent decrease is 78.75%
Answer:
![h+3s= 35--------1\\\\2h+s= 20--------2](https://tex.z-dn.net/?f=h%2B3s%3D%2035--------1%5C%5C%5C%5C2h%2Bs%3D%2020--------2)
Step-by-step explanation:
Given data
let hats be h
and shirts be s
Rob brought a hat and 3 shirts for 35$. Dan brought 2 hats
h+3s= 35--------1
and a shirt for 20$
2h+s= 20--------2
Hence the systems of equations is given as
h+3s= 35--------1
2h+s= 20--------2
Answer:
Step-by-step explanation:
(9√5) (5√10)
The leading interger product is found by multiplying 9 and 5
The leading integer product is 9*5 = 45
The radical product is (√5*10
Factor 10
radical product = √5*2*5
There are 2 fives underneath the radical. Take one out and ignore the other
radical product = 5√2
The 5 now multiplies by 45 and √2 becomes part of the answer
5*45√2
225√2
