Answer:
210.25 pi in^2.
Step-by-step explanation:
Diameter = 14.5 inches so the radius = 1/2 * 14.5 = 7.25 inches.
So the surface area of the sphere = 4 pi r^2
= 4 * pi * 7.25^2
= 210.25 pi in^2.
fourth one
I believe the answer would be 36.
Hope this helped you. ;}
15:25
3000
a decrease in the ratio 5:3 implies that:
new quantity :old quantity :5:3
let new quantity be x.
x:1800=5:3
x/1800=5/3
3x=9000
x=9000/3
x=3000
