Jake volunteers to out his younger brother's basketball team in his free time. one of his tasks is to ensure that all the basketballs have enough air in them. given that a properly inflated basketball measures 8.8 inches across, what is the total volume of air inside six of jake’s basketballs? assume that the wall of each ball is infinitely thin.

681.47 cubic inches
1,651.32 cubic inches
3,775.23 cubic inches
5,451.78 cubic inches

681.47 π cubic inches

Step-by-step explanation:

Given : A properly inflated basketball measures 8.8 inches across.

To Find: What is the total volume of air inside six of Jake’s basketballs?

Solution:

Diameter of ball = 8.8 inches

Radius = Diameter/2 = 8.8/2 = 4.4

Since we need to calculate the volume of air inside the ball which is in the shape of sphere

So, formula we will use

Volume of sphere =

Where r is radius and use π =3.14

Thus the volume of air inside the ball =

                                                               =

                                                              =

since there are 6 balls

So, Volume of air in 6 balls =

                                            =

Hence the volume of air in six balls 681.47 π cubic inches

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

6/20
