5 and 1 you multiple 5*1 to get 5 and add 5+1 to get 6
6*4=24
8*6=48
24/48=4/8=1/2
I hope this helps;)
Answer:
100 pi cm^2
or approximately 314 cm^2
Step-by-step explanation:
The surface area of a sphere is given by
SA = 4 pi r^2
The radius is 5
SA = 4 *pi * 5^2
SA = 4*pi(25
SA = 100 pi cm^2
If pi is 3.14
SA = 100 *3.14 = 314 cm^2
30%÷100% = 0.30; $85×0.30= $25.50; 85 - 25.50= $59.50.
15%÷100% = 0.15; $59.5 ×0.15 =8.92; 59.50 - 8.92= $50.58
$50.58
