2. 164centimeter2 (exponent po yang 2)

3. 208 feet2 (exponent po yang 2)

4. 62.66251815409 decameters2 (exponent po yang 2)

5. 864 centimeters2 (exponent po yang 2)

6. 100.53096491487 meters2 (exponent po yang 2)

Step-by-step explanation:

1. Surface Area =  4πr2

=  4×π×72

=  196π

=  615.7521601036 centimeters2 (exponent po yang 2)

2. Base Surface Area = s2

= (10)2 = 100 centimeter2

Side surface Area = 1/2 x b x h

= 1/2 x 4 cm x 8 cm

=1/2 (32 cm2)

= 16 cm2

Area of 4 sides = 4 x 16cm2 = 64 cm2

Total surface Area = 100cm2 + 64cm2 = 164cm2

3.Surface Area = 2×(8×6 + 8×4 + 6×4) = 208 feet2

4. Base Surface Area =  π×42

=  50.265482457437 decameters2

Lateral Surface Area =  π×4×√42 + 82

=  112.39703569665 decameters2

Total Surface Area = 162.66251815409 decameters2

5. Surface Area = 6×122 = 864 centimeters2

6. Top Surface Area =  π×22

=  12.566370614359 meters2

Bottom Surface Area =  π×22

=  12.566370614359 meters2

Lateral Surface Area =  2π×2×6

=  75.398223686155 meters2

Total Surface Area = 100.53096491487 meters2
