Answer:
<em>8 units</em>
Step-by-step explanation:
Given the relationship between the radius, r, of a sphere and its surface area, A expressed as;
r = 1/2( A /4 π )
We are to find the radius r when Area A is 64π
Substitute A = 64π into the expression and get r as shown;
Recall that: r = 1/2( A /4 π )
r = 1/2( 64 π/4 π )
r = 1/2(16)
r = 16/2
r = 8units
<em>Hence the radius of the sphere will be 8 units</em>
Answer:
Step-by-step explanation:
The quotient of 4 and 8 is ...
To increase 9 by that amount, you have to add that amount to 9:
Answer:
$0.25r + $5 = $12.50
Step-by-step explanation:
r represents the amount of rides Lacy went on during the day. If you do the problem in the correct order, you will get the answer
Step 1)
Subtract 5 from both sides
$0.25r + 5 (-5) = 12.50 (-5)
Step 2)
Divide by 0.25
0.25r (Divided by 0.25) = 7.50 (Divided by 0.25)
Step 3)
Answer
r = 30 rides
Answer:
<h2>4 is the right answer</h2>
<h2>2 × 2 = 4</h2>
<h3>2 × 1 = 2 </h3><h3>2 × 2 = 4</h3><h3>2 × 3 = 6 </h3><h3>2 × 4 = 8</h3><h3>2 × 5 = 10</h3><h3>2 × 6 = 12</h3><h3>2 × 7 = 14</h3><h3>2 × 8 = 16</h3><h3>2 × 9 = 18</h3><h3>2 × 10 = 20</h3>
<h2>Why is 2+2=4 and 2x2=4? </h2>
<h3>Originally Answered: why does 2*2=4 and 2+2=4? The truth is that a number multiplied by itself does not have to be equal to the same number added to itself. We can prove 2x2=4 easily. We have 2 groups of 2s.</h3>
