The formula for the volume of a cone is
v = ( 1 / 3) h pi r^2
where h is the height of the cone
pi is 3.1416
r is the radius of the cone
since diameter is given
D = 2r
r = D/2 = 4/2 = 2 in
substitute the given
V = (1/3) (6) (3.1416) (2^2)
V = 25.1 cubic in
Answer:
£5083
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 2.1%/100 = 0.021 per year,
then, solving our equation
I = 4600 × 0.021 × 5 = 483
I = £ 483.00
The simple interest accumulated
on a principal of £ 4,600.00
at a rate of 2.1% per year
for 5 years is £ 483.00.
Answer:
a) f(0)=2
b)f(2)=-4
c)f(0)+f(2)=-2
d)f(3)*f(-2)=-56
e)f(0):f(2)=-1/2
Step-by-step explanation:
f(x) =-3x+2
a) f(0)=-3*0+2=2
b) f(2)=-3*2+2=-6+2=-4
c) f(0)+f(2)=2-4=-2
d)f(3)*f(-2)=-7*8=-56
f(3)=-3*3+2=-9+2=-7
f(-2)=-3*(-2)+2=6+2=8
e)f(0):f(2)=2/(-4)=-1/2
