180 - 79
101 degrees is the answer
I think the answer would be c. I mean, I know I wouldn't choose a bank 'cause it offered a prize. Hope this helps!
Answer:
the volume of a cone = 1589.625feet³
Step-by-step explanation:
given that the diameter of the cone = 15inches
radius = 15inches/2 = 7.5inches
height of the cone = 27 inches
volume of the cone = ?
recall that
the formulae for finding the volume of a cone is given to be
= 1/3πr²h
the volume of a cone = πr² h/3
the volume of a cone = 3.14 × ( 7.5)² × 27/3
the volume of a cone = (3.14 x 56.25 x27)/3
the volume of a cone = 4768.875/3
the volume of a cone = 1589.625feet³
Answer:
The sum of geometric series is 716144
Step-by-step explanation:
Given
First term=a_1= -11
Last term=a_8=859375
Common ration of geometric series=r= -5
And
Total terms in geometric sequence=n=8
We know that the formula for sum of geometric series is:
S_n= (a_1 (1-r^n))/(1-r)
= (-11(1-(-5)^8)/(1-(-5))
= (-11(1-5^8))/(1+5)
= (-11(1-390625))/6
=(-11(-390624)))/6
=4296864/6
=716144
So the sum of geometric series is: 716144 ..
