Answer:
804.25 cm² (corrected to 2 decimal places)
Step-by-step explanation:
Radius = diameter / 2
= 16/ 2
=8 cm
Surface area of sphere = 4πr²
= 4π8²
=804.25 cm² (corrected to 2 decimal places)
1. 641
2. 65.4
3. 21+7=28 total marbles. The greatest number of groups would be 7, with 1 blue and 3 white.
4. 80% of 685= .80 x 685= 548 students.
Marked down by 35%
this decreased it by 115.65
thhat means that 115.65 is 35% of original
find original
35%=35/100=7/20
'of' means multiply
115.65=7/20 times original
multiply both sides by 20/7 to clear fraction (20/7 times 7/20=140/140=1)
2313/7=original
330.428=original
round
330.43
original price=$330.43
D. 32/47
You would subtract 1580 from 640 to get 940. You would then simplify 640/940 to get 32/47.
