The value of the given expression is 11.57
<h3>Division of number</h3>
Division are written as a ratio of two values. Given the expression below
5+6+6+2^6 ÷ 7
Simplify to have:
(11+6+64)÷ 7
Simplify the expression in parenthesis
81÷ 7
11.57
Hence the value of the given expression is 11.57

Answer: 4. -12
4. 9
6.17
Step-by-step explanation:
Whooh
SA=4pir²
take derivitive
dSA/dt=8pir dr/dt
and do the volume as well
V=(4/3)pir³
dV/dt=4pir² dr/dt
we need to solve for dV/dt
to do taht we need dr/dt
so
dSA/dt=8pir dr/dt
given dSA/dt=3pi cm/sec
r=2
3pi=8pi2 dr/dt
3=16 dr/dt
3/16=dr/dt
now do the volume
dV/dt=4pir² dr/dt
r=2
dr/dt=3/16
dV/dt=4pi2² (3/16)
dV/dt=16pi(3/16)
dV/dt=3pi
nice
the volume of the sphere is decreasing at 3pi cm/sec as well
