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
The real cube root is 0.03 because...
(0.000027)^1/3 = (27 x 10^-6)^1/3 = 3 x 10^-2 = 0.03
Use the Pythagorean theorem (a^2 + b^2 = c^2)
7^2 + 24^2 = x^2
x^2 = 625
x = 25
