(ignore the f and s part i just need the lateral and total)

PLEASE PLEASE HELP IM BEGGING YOU

Answer 1

Answer:

Step-by-step explanation:

1.

Base area = πr² = 6²π = 36π in²

Circumference = 2πr = 12π in

Lateral area = 2πrh = 144π in²

Total surface area = 2×36π + 144π

= 216π in²

2.

Base area = πr² = π3.25² = 10.5625π in²

Circumference = 2πr = 6.5π in

Lateral area = 2πrh = 6.5π×6.2 = 40.3π in²

Total surface area = 2×10.5625π + 40.3π = 61.425π in²
