Answer:
72ft²
Step-by-step explanation:
Calculate the area of each face and then sum them.
area of base = 4 × 5 = 20 ft²
area of back = 5 × 3 = 15 ft²
area of sloping face = 5 × 5 = 25 ft²
area of 2 triangular faces = 2 × × 4 × 3 = 4 × 3 = 12 ft²
Thus
surface area = 20 + 15 + 25 + 12 = 72 ft²

Answer:
f(6) = 82
Step-by-step explanation:
substitute x = 6 into f(x) and evaluate
f(6) = 2(6)² + 5 = 2(36) + 5 = 72 + 5(2) = 72 + 10 = 82

Answer:
V = πr²h
r = √V/πh
r = √8281 cm³/(3.14)(23 cm)
r = √8281 cm³/72.22 cm
r = √114.66 cm²
r = 10.71 cm
