Answer:
Area of shaded region = 16π in² (D)
Step-by-step explanation:
The question is incomplete without the diagram if the circles. Find attached the diagram used in solving the question.
Area of the smaller circle = 8π in²
Area of a circle = πr²
πr² = 8π
r² =8
r = √8 = 2√2
From the diagram, there are two smaller circles in a bigger circle.
The radius of the bigger circle (R) is 2times the radius of the smaller circle (r)
R = 2r
Area of bigger circle = πR²
= π×(2r)² = π×(2×2√2)²
= π×(4√2)² = π×16×(√2)²
Area of bigger circle = π×16×2
Area of bigger circle = 32π in²
Since there are two smaller circles in a bigger circle
Area of shaded region = Area of bigger circle -2(area of smaller circles)
Area of shaded region = 32π in² - 2(8π in²)
Area of shaded region = 32π in² - 16π in²
Area of shaded region = 16π in²
Area of a rectangle is Length times width
So basically 380 * 280 should be the answer
The answer should be 106400
Group 1:-
5 cookies
3 people
5/3
Group 2:
8 cookies
6 people
8/6
Group 1 each person gets 5/3 and in group 2 each person gets 8/6.
Which is more?
5/3
5 ÷ 3 ≈ 1.6
8/6
8 ÷ 6 ≈ 1.3
Is 1.3 more or 1.6?
1.6 is more.
5/3 (group 1) receive more.
Answer:
20 years
Step-by-step explanation:
20 is the lowest common multiple of 5,4,2
<em>40</em>
- Step-by-step explanation:
<em>2 + 10 = 24</em>
<em>2(2 + 10) = 2×12 = 24</em>
<em>3 + 6 = 27</em>
<em>3(3 + 6) = 3×9 = 27</em>
<em>7 + 2 = 63</em>
<em>7(7 + 2) = 7×9 = 63</em>
<em>5 + 3 = 40</em>
<em>5(5 + 3) = 5×8 = 40</em>
