Answer:
48π + 120
Step-by-step explanation:
Lateral area of a cylinder = Ch = πdh
1/4 of the lateral area = 12π(10)/4 = 30π
Bottom area = 6(10) = 60
Front area = 6(10) = 60
Area of base = πr^2/4 = 36π/4 = 9π
Area of two bases = 18π
Total area = 18π + 30π + 60 + 60 = 48π + 120

Answer:
b = 16
Step-by-step explanation:
16*x + b*x + 4 = 0
Solving for x we get:
x₁,₂ = - b ± √ b² - 4*a*c ] / 2*a (1)
If we take a look to the square root
√ b² - 4*4*16 = √ b² - 256
if we make √ b² - 256 = 0
b² = 256 ⇒ b = 16
Then equation (1) becomes:
x₁,₂ = ( - 16 ± 0 ) / 32
x = - 1/2

Answer: The probability that the sum is less 7 or less is 20/51.
First, we start by selecting an ace because the question says one card is an ace. Therefore, our final probability is out of 51.
Our goal is to have 7 or less. That means we can draw a 2, 3, 4, 5, or 6. Since, there are 4 of each type, we have 4 x 5 = 20 different possibilities.
