Answer:
130.43 cm³
Step-by-step explanation:
To find the difference between the volumes of the balls, we must first find the volumes of the balls. To find the volume of each ball, we must first determine their shape. We understand that both balls are spherical.
The volume V of a sphere wit radius r is given as
V = 4/3 πr³
where r is the result when the diameter of the sphere is divided by 2.
Hence the radius of the Golf ball
= 4.3cm/2
= 2.15cm
radius of the tennis ball
= 6.9cm/2
= 3.45cm
The difference between the volumes of the two balls
= 4/3 π (3.45³ - 2.15³)
= 130.43 cm³
Answer:
-96.22 is not an integer.
Step-by-step explanation:
An integer is just basically whole numbers, which including no decimals, and fractions.
Note: Some decimals and fractions can be converted to whole numbers, meaning, they are intergers.
On the other hand, -96.22 can not become a whole number, concluded that it is not an interger.
Answer:11:7 that’s the simplest it can be
Sodas+hot dogs = 231
hotdogs* 2 = sodas
substitute,
hotdogs*2 +hotdogs= 231
3*hotdogs = 231
hotdogs = 77
sodas = 154
