The spherical water storage tank with a radius of 10 ft can hold approximately 31,391.93 gallons of water after calculating its volume and converting to gallons. The volume is calculated using the formula for a sphere and then using the conversion rate from cubic feet to gallons. Thus, the total volume in gallons is roughly 31,391.93.

Jawab:a). 2, 4, 6, 8, 10, ...Diketahui:• Suku pertama (a) = 2• Beda (b) = 4 - 2 = 2Maka, Un = a + (n - 1)bUn = 2 + (n - 1)2Un = 2 + 2n - 2Un = 2nb). 1, 9, 25, 49, ...Menentukan pola barisan:1³, 3², 5², 7², ...Maka,Un = (2n - 1)²Jadi suku ke-n nya adalah Un = (2n - 1)²
