The volume of the sphere is 900 cm³
Step-by-step explanation:
- Step 1: Given the diameter of the ball = 12 cm. Find radius.
Radius = diameter/2 = 12/2 = 6cm
- Use the formula for volume of a sphere to find the volume.
Volume of the ball = 4/3 πr³
= 4/3 × 3.14 × (6)³
= 904.32 cm³ ≈ 900 cm³ (nearest hundredth)

Multiply across the rows to form a third column. Example: 9*90 = 810 in the first row.
![\begin{array}{|c|c|c|} \cline{1-3}\text{Number of People} & \text{Score} & \text{Number*Score}\\\cline{1-3}9 & 90 & 810\\\cline{1-3}18 & 80 & 1440\\\cline{1-3}15 & 70 & 1050\\\cline{1-3}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7B%7Cc%7Cc%7Cc%7C%7D%20%5Ccline%7B1-3%7D%5Ctext%7BNumber%20of%20People%7D%20%26%20%5Ctext%7BScore%7D%20%26%20%5Ctext%7BNumber%2AScore%7D%5C%5C%5Ccline%7B1-3%7D9%20%26%2090%20%26%20810%5C%5C%5Ccline%7B1-3%7D18%20%26%2080%20%26%201440%5C%5C%5Ccline%7B1-3%7D15%20%26%2070%20%26%201050%5C%5C%5Ccline%7B1-3%7D%5Cend%7Barray%7D)
The values in the third column add to 810+1440+1050 = 3300
Divide this over the total number of people which is 9+18+15 = 42
The mean is 3300/42 =78.571 approximately which rounds to 78.6
Answer:
14.85
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh where b is the base and h is the height
A =1/2 ( 6.6)(4.5)
A = 14.85
Weeeeelllll, when dividing lets say long division 4 58..... Nevermind this topic is like so easy and your in highschool
