Answer:
Minimum 7 buckets of water is needed to completely fill spherical storage tank.
Step-by-step explanation:
We are given the following in the question:
Cylindrical bucket:
Radius, r = 6 inches
Height = 18 inches
Volume of bucket = Volume of cylinder
Spherical storage tank:
Radius, r = 15 inches
Volume of tank = Volume of sphere =
Number of baskets required =
Thus, minimum 7 buckets of water is needed to completely fill spherical storage tank.
rational, because irrational numbers go on forever and ever
this decimal stops at 7, if a number has an end to it it's rational
an irrational number would be π (pi) since it goes on forever
Answer:
26.22in²
Step-by-step explanation:
First get the radius using the formula of a circumference.
C = 2πr = 18.2
2(3.14)r = 18.2
6.28r = 18.2
Divide both sides by 6.28 to get r
r = 2.89
Now get the area of a circle using the formula:
A = πr²
A = 3.14(2.89)²
A = 3.14(8.35)
A = 26.22in²
Answer:
50degrees
Step-by-step explanation:
The sum of angle in the triangle XYZ is 180degrees, hence;
<X + <Y + <Z = 180
Given
m<X = 80degree
m<Y = m<Z
Required
m<Z
Substitute the given angle
80 + m<Z + m<Z = 180
80 + 2m<Z = 180
2m<Z = 180 - 80
2m<Z = 100
m<Z = 100/2
m<Z = 50degrees
Hence the measure of angle Z is 50degrees
