Answer:
<h3>Surface Area = 1,256 cm</h3>
<u>Solution:</u>
formula: Surface Area of a Sphere: 4π · r²
Surface area = 4π · r²
SA = 4(3.14) (10)²
SA = (12.56)(100)
SA = 1,256
A = 3,953 in²
You find the area of the whole triangle:
1/2bh = 1/2(63+31)(63+62) = 5875
Then subtract the missing rectangle:
lw = (62)(31) = 1922
5875 - 1922 = 3953 inches
Since you're multiplying inches by inches, it's inches².
Answer:
15 packages
Step-by-step explanation:
Set up a proportion, where x is the number of packages she can wrap with 2.5 rolls of wrapping paper:
= 
Cross multiply and solve for x:
0.5x = 7.5
x = 15
So, with 2.5 rolls of wrapping paper, she can wrap 15 packages
