Answer:
The volume of the cylinder in feet is
V= 9.43ft³
Step-by-step explanation:
Step one
The formula for the volume of a cylinder is given as
V=πr²h
Where r= radius
h= height
Step two
Given Data
Radius = 1foot
Height = 3 feet
Substituting in our formula we have
V=3.142*1²*3
V= 9.43ft³
The probability that the value selected at random is greater than 30 will be found as follows:
z-score is given by:
z=(x-mu)/sig
z=(30-30)/2=0
thus
P(x>30)=1-P(X<30)=1-P(z<0)=1-0.5=0.5
Answer P(x>30)=0.5
The measure of the angle <u>x = 90°</u>
<u>Theorem Of Tangent</u>:-
A radius is obtained by joining the centre and the point of tangency. The <u>tangent at a point on a circle is at right angles to this radius</u>.
