Volume= pi times radius squared times height.
So the diameter is 16, if you divide by 2 you'll get the radius. 16/2=8
So the answer is 3.14x8^2x10
8 squared is 64
So 3.14x64x10 = 2,010.62
Answer is C

Given the polynomial function below, find F(-1). F(x) = -x ^3 - x ^2 + 1

steposvetlana [31]

Answer:

$f(-1) = 1$

Step-by-step explanation:

Given

f(x) = $-x^{3}-x^{2} +1$

Finding f(-1) means, we have to put -1 in the places of x in the function,

So, putting x=-1 in the function

$f(-1) = (-1)^{3} - (1)^{2} +1$

As the power 3 is odd, the minus will remain the same, while in the 2nd term minus will be eliminated due to even power. So,

=> $-1-1+1$

=> 1

Hence,

$f(-1) = 1$

{1,2,3,...75,76,77,78}

Vinvika [58]

Answer:

Step-by-step explanation:

even numbers are 2,4,6,...,78

it is an A.P.

first term a=2

c.d. d=4-2=2

an=a+(n-1)d

78=2+(n-1)2

76=(n-1)2

n-1=76/2=38

n=38+1=39

now we take multiples of 10

10,20,30,...,70

70=10+(n-1)10

60=(n-1)10

n-1=60/10=6

n=6+1=7

so reqd. number of numbers=39-7=32
