What is the volume of a hemisphere with a diameter of 8.6 ft, rounded to the nearest tenth of a cubic foot? \text{Volume of a Sphere:}

volumeV = 166.519071 ft^3

Step-by-step explanation:

radiusr = 4.3 ft

base circumferenceC = 27.0176968 ft

volumeV = 166.519071 ft^3

curved surface areaA = 116.176096 ft^2

base surface areaB = 58.0880482 ft^2

total surface areaK = 174.264144 ft^2

In Terms of Pi π

base circumferenceC = 8.6 π ft

volumeV = 53.0046667 π ft^3

curved surface areaA = 36.98 π ft^2

base surface areaB = 18.49 π ft^2

total surface areaK = 55.47 π ft^2

Volume of a hemisphere:

V = (2/3)πr^3

answer: 4

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
