Answer:
502.4 in²
Step-by-step explanation:
Area of a sphere = 4 πr²
Plastic beach balls are spherical in shape.
Hence, the Area of a sphere = 4πr²
Where r = radius = 2 inches
π = 3.14
Hence, the area of one spherical ball =
4 × 3.14 × 2²
= 50.24 square Inches
For 1 spherical ball, 50.24 square inches of plastic is needed to make it.
How many square inches of plastic does the company need to make 10 beach balls?
Therefore,
1 spherical ball = 50.24 in²
10 spherical balls = x
Cross Multiply
x = 10 × 50.24 in²
x = 502.4 in²
Therefore, 502.4 square inches of plastic is needed by the company to make 10 beach balls.
Answer:
it would take Edward 8 to pay back his debt
Step-by-step explanation:
every 2 days he pays his parents 5 bucks so because 5 times 4 equals 20 he would have to multiply the 4 by 2 and that gets you 8 days
Hey there! Your question’s answer would be 18%..
Ok so 9/50 would be 9% out of 50% which is also 100%. If you want to find 50% turn to 100%, multiply 50 with 2 to get 100.
So you do the same thing to 9%. 9 times 2 would be 18%.
Final Result: 9% out of 100% (whole)
I know for a fact that #1 is wrong. its supposed to be 18. for the median height of giraffes. and #2 is correct 63 acres. but im not sure how to do a leaf plot .
