The formula for lateral area is pi x radius x height
If the diameter is 18, the radius is 9
3.14 x 9 x 48 = 1356.48
Answer:
The answer to your question is 43.7 g of chocolate
Step-by-step explanation:
Data
56% cocoa
mass of a chocolate bar = 78 g
Process
To solve this problem, use proportions and cross multiplication, consider the mass of the bar is 100%.
78 g of chocolate ------------------- 100%
x ------------------ 56%
x = (56 x 78) / 100
x = 4368/100
x = 43.68 g
-Round to the nearest tenth
Mass of the chocolate = 43.7 g
The answer would be
7/11=0.6363636364
x + y = 3
- x - x
y = -x + 3
y - y₁ = m(x - x₁)
y - (-1) = -1[x - (-1)]
y + 1 = -1(x + 1)
y + 1 = -1(x) - 1(1)
y + 1 = -x - 1
- 1 - 1
y = -x - 2
The answer is B.
4, 12, and 18 in two different ways
<span>(4 + 12) + 18 = 16 + 18 = 34
4 + (12 + 18) = 4 + 30 = 34
answer is B) </span><span>(4 + 12) + 18 = 16 + 18 = 34; 4 + (12 + 18) = 4 + 30 = 34 (second choice)</span>
