Answer:
Sa = 1.5*V
Step-by-step explanation:
We have that the surface area of a sphere has the following formula:
Sa = 4*pi*r^2
we know that r = 2, so if we replace it, we're left:
Sa = 4*pi*(2^2)= = 4*pi*4
Sa = 16*pi
Now, the volume has the following formula:
V = 4/3*pi* r^3
Replacing it is our job:
V = 4/3*pi* (2^3) = 4/3*pi*8
V = 32/3*pi
Now, Sa/V, it would remain:
Sa/V = 16*pi / 32/3*pi
Sa/V = 48/32 = 1.5
Therefore, Sa = 1.5*V
Answer:
4 hours. 1 3/4 is about 2, and 2 1/4 rounds to 2. 1/4 would round to 0, but it would not affect the estimate's accuracy much because we rounded up by 1/4 on 1 3/4 already. Philipe spent about 4 hours on activities.

Answer:
Aisha gross pay equals $472
Step-by-step explanation:
If Aishat is paid $8.00 per hour, then for 39 hours, she will get
39 × 8 = $312
She gets 4% commission on all sales. If her sale is $4000, the her commission will be
4000 × 4/100
= $160
Then her total gross income will be $312 + $160 = $472
12 days. 60 is a quarter of 240. So, multiply 60 by 4 to get 240.
