A cone and its dimensions are shown in the diagram. What is the volume of the cone in cubic inches?
Vinvika [58]

Answer:

The exact value of the volume is equal to

V=19\frac{397}{512}\pi\ in^{3}

Step-by-step explanation:

we know that

The volume of a cone is equal to

V=\frac{1}{3}\pi r^{2} h

we have

D=5\frac{5}{8}\ in

convert to an improper fraction

D=5\frac{5}{8}\ in=\frac{5*8+5}{8}=\frac{45}{8}\ in

r=(45/8)/2=\frac{45}{16}\ in

h=7\frac{1}{2}\ in=\frac{7*2+1}{2}=\frac{15}{2}\ in

substitute in the formula of volume

V=\frac{1}{3}\pi (\frac{45}{16}^{2})(\frac{15}{2})=\frac{30,375}{1,536}\pi\ in^{3}

Simplify  

\frac{30,375}{1,536}=\frac{29,184}{1,536}+\frac{1,191}{1,536}=19\frac{397}{512}

substitute

V=19\frac{397}{512}\pi\ in^{3}

A microwave is the only electric device in a 120-volt circuit. If the circuit has 7.5
bogdanovich [222]

The electric power of microwave is 900 watts.

Step-by-step explanation:

Given,

Voltage in the circuit = 120 volts

Current in the circuit = 7.5 amp

Electric power of microwave = Voltage*Current

Electric power of microwave = 120*7.5

Electric power of microwave = 900 watts

Therefore,

The electric power of microwave is 900 watts.
