What is the diameter of a hemisphere with a volume of 863 in', to the nearest tenth
of an inch?

Diameter of a hemisphere: d = 2 * r ,

Volume of a hemisphere: V = 2/3 * π * r³ ,

Base surface area of a hemisphere: Ab = π * r² ,

Cap surface area of a hemisphere: Ac = 2 * π * r² ,

Total surface area of a hemisphere: A = 3 * π * r² ,

We know that for a hemisphere whose radius is 9 units, The volume is: Volume of hemisphere=2πr33 Volume of hemisphere = 2 π r 3 3

Step-by-step explanation:

Answe 33.2

Step-by-step explanation:

863÷3.14=274.8407643312 find the square root then multiply by 2

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
