Considering the ballon to be spherical
It's volume is given by 4/3(π r^3) by differentiating volume with respect to time we get rate of change of volume hence,
4πr^2(dr/dt)=600÷60=10
Substituting r=30cm
4π(30)*(30)(dr/dt)=10
dr/dt=rate of increase in bullion's radius=1/(360π)cm/s
-2 to the 7th power is -128.
Answer:
(-6,-7) or (-3,-8)
Step-by-step explanation:
Answer:
15 degrees.
Step-by-step directions:
It is 15 degrees because the angle there is 90 degrees in total. And one of the angles are 75 degrees. So, 90-75 equals 15 degrees.
Answer:
48
Step-by-step explanation:
8 divided by 2 = 4
