Answer:

77.03 cm²

Step-by-step explanation:

The appropriate formulas are ...

CSA = Ch . . . . . curved surface area, C=circumference, h=height

where

C = πd

d = C/π

Here, we have ...

h = 2d = 2C/π

C = 11 cm

so the curved surface area is ...

CSA = (11 cm)(2(11 cm)/π) = 242/π cm² ≈ 77.03 cm²

The number of teams who entered in a 3-on-3 charity basketball tournament can be modeled by function T, where x is the number of

Answer:

<u>Option A:</u>

$R(x)=20x^2+300x+1080$

Explanation:

The revenue, R(x) is the product of the number of teams who entered the tournament, T(x), times the entry fee paid by each team, F(x); then you can write:

$R(x)=T(x)\times F(x)$

Thus you must multiply the two functions (polynomials):

$R(x)=(4x+24)\times (5x+45)$

Use distributive property:

$R(x)=(4x+24)\times (5x+45)=(4x)(5x)+(4x)(45)+(24)(5x)+(24)(45)$

Simplify:

$R(x)=(4x)(5x)+(4x)(45)+(24)(5x)+(24)(45)=20x^2+180x+120x+1080$

Add like terms:

$R(x)=20x^2+180x+120x+1080=20x^2+300x+1080$
