Answer:
x² +y² = 16
Step-by-step explanation:
The diagonal of a square is √2 times the side length, so the diameter of a circumscribed circle is √2 times the diameter of an inscribed circle. Each of the two outer circles is √2 times the diameter of the one just inside it, so the outer circle is (√2)(√2) = 2 times the diameter of the inner circle.
The equation of the largest circle with radius 2·2=4 is ...
x² +y² = 16
The answer is 30; you add the 10 to the 20
To write in the scientific notation, we have to move the decimal point to the left of the number given until it reaches the first number multiply it by ten and raise to a number equal to the number of times you move the decimal point. Therefore, the correct answer is 3.92 x 10^12.
Answer:
Step-by-step explanation:
<u>The volume formula:</u>
<u>Given:</u>
- d = 0.75 in ⇒ r = d/2 = 0.75/2 in
- h = 0.04 in
<u>The volume of each penny:</u>
<u>The volume of 100 pennies:</u>
- V = 100*π(0.75/2)²(0.04) = π(0.75/2)²(4)
Correct choice is B
The correct answer is 10/7 or 1 3/7. Hope this helps.
