Step-by-step explanation:
Formula: SA = 2
rh + 2
r²
SA = 2
rh + 2
r²
SA = 2(3.14)(5)(4) + 2(3.14)(5)
SA = 2(3.14)(5)(4) + 2(3.14)(25)
SA = 125.6 + 157
SA = 282.6 cm²
In a four-digit number, the first digit cannot be 0, so there are only 4 even numbers available. For the second, third, and fourth digits, there are 5 available numbers. Thus, the number of 4-digit numbers containing only even digits is 4 x 5 x 5 x 5 = 500 numbers.
