Circumference is 40 in and area is 150 in²
Step-by-step explanation:
- Step 1: Find the circumference of the circle when radius = 7 in
Circumference = 2πr = 2 × 22/7 × 7 = 44 in ≈ 40 in
- Step 2: Find the area of the circle.
Area = πr² = 22/7 × 7² = 154 in² ≈ 150 in²
Answer:
30+4+0.7+0.05
Step-by-step explanation:
Because the expanded form is added the number.
3=30
4=4.
7=0.7
and 5=0.05 so all together is 30+4+0.7+0.05
(x+3)(x+3) = x^2 -3 + 3x
x^2 + 3x + 3x + 9 = x^2 + 3x - 3
x^2 + 6x + 9 = x^2 + 3x - 3
6x + 9 = 3x - 3
3x + 9 = -3
3x = -12
x = -4
Check:
(-4+3)^2 = (-4)^2 - 3(1+4)
(-1)^2 = 16 - 3(5)
1 = 16-15
1 = 1 :)
<span><span>We are told the reduced fat milk has 41.25% less fat than whole milk.
So the reduced fat milk has 58.75% of the fat of whole milk (that is, 100% -41.25%).
A serving of whole milk has 8 grams of fat.
So a serving of reduced fat milk has .5875 * 8 g = 4.7 g of fat.</span><span>
