Formula of the Volume of a hemisphere:
V =
r³
144
=
r³
Multiply by 3 to cancel fraction in the right side
144
× 3 = 2
r³
432
= 2
r³
Divide by 2
on either sides to isolate r³
=
r³
2
and
cancel out
216 = r³
Take cube root to find the radius
=
6 = r
Radius is 6 unitsThe formula of the surface area of a hemisphere is:
S.A = 2
r² +
r²
=
(6)² +
(6)²
=2
× 36 + 36
= 72
+ 36
= 108
units² (in terms of
)
≈ 339.12 units²
Surface area = 108 units
Answer:
4.103, 4.13, 4.1, 4.1031
Step-by-step explanation:
if u reduced the price by 10% first it would go from 100% to 90%
20% of 90 is 18
at the end the price is 72% of the original price.
Bodil is correct. The reduction is less than 30%.
Answer:
all non-negative real numbers, [0, ∞)
Step-by-step explanation:
Replacing x in the parent function √x with (x+5) shifts the graph horizontally, but has no effect on the vertical extent of the graph. It still ranges from 0 to +∞.
The range of √(x+5) is [0, ∞).
<u>Answer-</u>
<em>Mary should pour </em><em>150.8 in³</em><em> water into the vase.</em>
<u>Solution-</u>
The volume of the cylinder is given by,
Where,
r = base circle radius = 3 in,
h = height of the cylinder = 8 in,
Putting the values,
As Mary has to fill the vase th, so the amount of water would be,
