Answer:
The volume of the air that the beach ball will hold is 113,142.85 cm³.
Step-by-step explanation:
Sphere:
- It is a three dimension shape.
- It has a center.
- Volume=
, r is the radius of it. - Surface area= 4πr².
Given that,
Ariel is filling a giant ball with air.
The ball is sphere in shape.
The volume of air = The volume of the ball.
The radius of the beach ball is 30 cm.
The volume of the ball is 
cm³
=36,000π cm³
=113,142.85 cm³
The volume of the air that the beach ball will hold is 113,142.85 cm³.

60% decrease
15 is 60% of 25
What is 60% of 25?
Y is 60% of 25
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 60% * 25
Converting percent to decimal:
p = 60%/100 = 0.6
Y = 0.6 * 25
Y = 15
Answer:
(7,-11)
Step-by-step explanation:
x'=x-3
or x=x'+3=4+3=7
y'=y+6
y=y'-6
or y=-5-6=-11
so original point was (7,-11)
