To calculate the surface area of a cylinder, we need to find the lateral surface area and the area of the two circular bases.
The formula for the lateral surface area of a cylinder is 2πrh, where r is the radius and h is the height.
For Can A:
Radius = 3.5 cm / 2 = 1.75 cm
Height = 12 cm
Lateral Surface Area (A) = 2π(1.75 cm)(12 cm) = 126π cm²
Base Area (A) = π(1.75 cm)² = 9.625π cm²
Total Surface Area (A) = 126π cm² + 2(9.625π cm²) = 145.25π cm²
For Can B:
Radius = 2.25 cm / 2 = 1.125 cm
Height = 10 cm
Lateral Surface Area (B) = 2π(1.125 cm)(10 cm) = 22.5π cm²
Base Area (B) = π(1.125 cm)² = 3.984375π cm²
Total Surface Area (B) = 22.5π cm² + 2(3.984375π cm²) = 30.46875π cm²
Comparing the total surface area of Can A and Can B:
145.25π cm² > 30.46875π cm²
Can A has a greater surface area than Can B by 114.78125π cm².

Can make sure? Cause I don’t want to get it wrong because u have been lying to me every time I ask my question then I get it wrong
I apologize for any confusion or mistakes in my previous responses. Let's double-check the calculations for the surface area of the two soda cans.
For Can A:
Radius = 3.5 cm / 2 = 1.75 cm
Height = 12 cm
Lateral Surface Area (A) = 2π(1.75 cm)(12 cm) = 126π cm²
Base Area (A) = π(1.75 cm)² = 9.625π cm²
Total Surface Area (A) = 126π cm² + 2(9.625π cm²) = 145.25π cm²
For Can B:
Radius = 2.25 cm / 2 = 1.125 cm
Height = 10 cm
Lateral Surface Area (B) = 2π(1.125 cm)(10 cm) = 22.5π cm²
Base Area (B) = π(1.125 cm)² = 3.984375π cm²
Total Surface Area (B) = 22.5π cm² + 2(3.984375π cm²) = 30.46875π cm²
Comparing the total surface area of Can A and Can B:
145.25π cm² (Can A) > 30.46875π cm² (Can B)
Therefore, based on the correct calculations, Can A indeed has a greater surface area than Can B by approximately 114.78125π cm².
For Can A:
Radius = 3.5 cm / 2 = 1.75 cm
Height = 12 cm
Lateral Surface Area (A) = 2π(1.75 cm)(12 cm) = 126π cm²
Base Area (A) = π(1.75 cm)² = 9.625π cm²
Total Surface Area (A) = 126π cm² + 2(9.625π cm²) = 145.25π cm²
For Can B:
Radius = 2.25 cm / 2 = 1.125 cm
Height = 10 cm
Lateral Surface Area (B) = 2π(1.125 cm)(10 cm) = 22.5π cm²
Base Area (B) = π(1.125 cm)² = 3.984375π cm²
Total Surface Area (B) = 22.5π cm² + 2(3.984375π cm²) = 30.46875π cm²
Comparing the total surface area of Can A and Can B:
145.25π cm² (Can A) > 30.46875π cm² (Can B)
Therefore, based on the correct calculations, Can A indeed has a greater surface area than Can B by approximately 114.78125π cm².

I don’t see that see that answer it only shows lower
Let's recheck the calculations one more time:
For can A:
Lateral Surface Area = 2 * π * radius * height = 2 * π * 1.75 cm * 12 cm ≈ 131.946 cm²
Base Area = π * (radius)² = π * (1.75 cm)² ≈ 9.625 cm²
Total Surface Area = Lateral Surface Area + 2 * Base Area ≈ 131.946 cm² + 2 * 9.625 cm² ≈ 151.196 cm²
For can B:
Lateral Surface Area = 2 * π * 1.125 cm * 10 cm ≈ 70.685 cm²
Base Area = π * (1.125 cm)² ≈ 3.984 cm²
Total Surface Area = Lateral Surface Area + 2 * Base Area ≈ 70.685 cm² + 2 * 3.984 cm² ≈ 78.653 cm²
Therefore, Can A has a greater surface area than Can B by approximately 72.543 cm² (151.196 cm² - 78.653 cm²).
For can A:
Lateral Surface Area = 2 * π * radius * height = 2 * π * 1.75 cm * 12 cm ≈ 131.946 cm²
Base Area = π * (radius)² = π * (1.75 cm)² ≈ 9.625 cm²
Total Surface Area = Lateral Surface Area + 2 * Base Area ≈ 131.946 cm² + 2 * 9.625 cm² ≈ 151.196 cm²
For can B:
Lateral Surface Area = 2 * π * 1.125 cm * 10 cm ≈ 70.685 cm²
Base Area = π * (1.125 cm)² ≈ 3.984 cm²
Total Surface Area = Lateral Surface Area + 2 * Base Area ≈ 70.685 cm² + 2 * 3.984 cm² ≈ 78.653 cm²
Therefore, Can A has a greater surface area than Can B by approximately 72.543 cm² (151.196 cm² - 78.653 cm²).
