The volume of a sphere is  (4/3) (pi) (radius)³ .

If the radius is 7cm, then the volume is

                                           (4/3) (pi) (7³)  = 

                                           (4/3) (pi) (343)  = 

                                            (457 and 1/3) (pi) cm³  (exact)

Answer:

5^15

Step-by-step explanation:

5^5 is 3125, and 5^10 is 9765625. When multiplied, you get 30517578125. 5^5 is in the equation, so that couldn't be the answer. 5^50 is too big of a number, so that also wouldn't work. 5^2 is 25, and that would be too small. That leaves 5^15, which when calculated leads to 30517578125.

Alona [7]

Answer: Option D) $13.12

Step-by-step explanation:

Alice submitted a bill of $82.00 at her first table, of which a tip of 16% was also given her.

So, to calculate the tip we say 16% of $82

i.e 16% of $82.00

= (16/100) of $82.00

= 0.16 x $82.00

= $13.12

Thus, Alice made $13.12 in tips at her first table at Angelina
