Answer:
D. She used the beach's ball's diameter when she should have used the radius
Step-by-step explanation:
To find the volume of the beach ball, using the volume of a sphere is the right formula to use, which is ⁴/3πr³.
The formula she used is correct.
Since the diameter of the ball is assumed to be 12 inches, what is needed to find the volume is the radius.
Radius (r) = ½(diameter) = ½(12) = 6 in.
This is where Emily made a mistake.
She used the diameter of the beach ball instead of its radius (r) which is needed in the equation.
She should have gotten,
V = ⁴/3(3.14)(6)² = 904.32 cubic inches
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
First term = 13
Increase each time = 20
Number of clients = 25
So, it forms an arithmetic progression:
So, 25 th term would be
Hence, list would look like 13,33,............493.
Therefore, Option 'D' is correct.
30,32,34,36,38,40,42,44,46,48,50
Answer:
y=−7−(√161/4), −7+(√161)/4
Decimal form- y=1.42214438, -4.92214438
Step-by-step explanation:
If you mean "how to write the sum", the answer is
The result of this sum is 
, because you start from 2 on the number line and take 3 steps to the left (negative integers mean going left, positive integers mean going right)
