Answer:

586.4 in

Step-by-step explanation:

i) V1 = πr²h

       = π x 4² x 9

       = 452.4

ii) V2 = 2/3 x π x r³

         = 2/3 x π x 4³

         = 134

iii) V = V1 + V2

    V = 452.4 + 134

        = 586.4

Can someone solve this
zysi [14]
You know how Soh Cah Toa applies to right triangles; you can assign the adjacent side = 4 and hypotenuse = 7

CosФ = (adjacent) / (hypotenuse)

Then with the Pythagorean theorem
4² + b² = 7²
16 + b² = 49
b² = 49 - 16
b² = 33
b = √(33)

So "b" is the opposite side.

SinФ = (opposite) / (hypotenuse) = √(33)/7
TanФ = (opposite) / (adjacent) = √(33)/4

Question 14 (1 point)
valina [46]

Answer:

C(x) = 25 + 2x

Step-by-step explanation:

He already has 25 cards.

He is collecting 2 cards per month. In x months, he will have collected:

2 * x = 2x cards

That means that the number of cards he will have after x months will be the sum of the cards he already has and the cards he collects per month:

C(x) = 25 + 2x
