You said that A = (s-2) 180
Divide each side by 180 : A/180 = s-2
Add 2 to each side: A/180 + 2 = s
we know that
Volume of a cone=(1/3)*[B]*h
where
B is he area of the base
h is the height
Find the volume of a cone in each case
case a) Raj
h=3 cm
diameter=5 cm
so
radius r=5/2=2.5 cm
Area of the base B=pi*r²
B=pi*2.5²
B=6.25*pi cm²
V=(1/3)*6.25*pi*3=6.25*pi cm³
case b) Amit
h=4 cm
r=3 cm
Area of the base B=pi*r²
B=pi*3²
B=9*pi cm²
V=(1/3)*9*pi*4=12*pi cm³
case c) Parul
h=7 cm
Area of the base B=4*pi cm²
V=(1/3)*4*pi*7=(9.33)*pi cm³
case d)Lara
h=6 cm
Area of the base B=3*pi cm²
V=(1/3)*3*pi*6=(6)*pi cm³
therefore
the answer is
Parul

Answer: 36.04 dollars</h3>
=============================================================
Explanation:
He gets a 15% discount, so he pays the remaining 85%. The two percentages add to 100%.
85% in decimal form is 0.85
The 6% sales tax means we also have the multiplier 1.06 to indicate a 6% increase.
The two factors 0.85 and 1.06 multiply to 0.85*1.06 = 0.901
This tells us that Andrew's father pays 90.1% of the original bill
0.901*40 = 36.04 dollars
--------------
An alternative method:
15% of $40 = 0.15*40 = 6
Andrew's father saves $6
The bill of $40 drops to 40-6 = 34 dollars before tax.
6% of $34 = 0.06*34 = 2.04
The father pays $2.04 in tax to get a total bill of 34+2.04 = 36.04 dollars
Answer:
x = 10
The both line crosses with a little hyphen, meaning those are same
