Answer:

  138.16 in²

Step-by-step explanation:

The surface area SA of the cone is the sum of the base area B and the lateral area LA. The lateral area is half the product of the circumference and the slant height. The radius is half the diameter, so is 4 inches.

  SA = B + LA

  = πr² + (1/2)(2πrh) . . . . where h is the slant height

  = (πr)(r +h)

Filling in the numbers, you have ...

  SA = (3.14)(4 in)(4 in + 7 in) = 3.14×(44 in²) = 138.16 in²

Paige was playing a trivia game where you gained points for correct answers and lost points for incorrect answers. At the start
victus00 [196]

Givens

Start = S = - 700

# Correct = C = 8

Value Correct = VC = 400

# Incorrect =I = 9

Value Incorrect =VI =  - 600

Equation

Score = S + C*VC + I*VI         Substitute

Solve

Score = -700 + 8*400 + 9(-600)

Score = -700 + 3200 - 5400

Score = - 700 - 2200

Score = - 2900 <<<<< Answer
