Answer:

Step-by-step explanation:
AD = BD (CD bisects AB means that it divides the line into two equal parts)
So,
AD = BD = AB/2
So,
AD = 3/2
AD = 1.5
<u><em>Now, Finding AC using Pythagorean Theorem:</em></u>

Where c is hypotenuse (AC), a is base (AD) and b is perpendicular (CD)



Taking sqrt on both sides

D/2=r
vcone=(1/3)hpir^2
given
d=30
h=9.1
d/2=30/2=15=r
v=(1/3)9.1pi15^2
v=(9.1/3)pi225
v=682.5pi
use 3.141592 to aprox pi
v=2144.13654
the closese is the first one
answer would be 2120 m³
Answer:
The student should have divided the discounted amount by the percent. The percent should have been written as a decimal.
Step-by-step explanation:
Answer:
The square root of terms separated by addition and subtraction cannot be calculated individually.
Step-by-step explanation:
In order to calculate the square root, we would need a monomial or a factored expression. We do not have that, so we cannot take the square root.
