Answer:(-11,0) and (11,0)
The Volume of sphere whose radius is 3 cm = 113 (rounded to the nearest tenth)
Volume= 113
The volume of a sphere = 4/3 r³, where r is the radius of the sphere.
Volume of sphere =
=
= 4 x 3.14 x 9
=113.04
≈ 113 (rounded to the nearest tenth)

The volume of a hemisphere with a radius of 3 cm is approximately 56.6 cm³ when rounded to the nearest tenth of a cubic centimeter. This is calculated by halving the volume of a sphere with the same radius.
The question asks for the volume of a hemisphere with a radius of 3 cm. The formula for the volume of a sphere is V = (4/3)πr³, and since a hemisphere is half of a sphere, the formula adapts to V = (1/2)(4/3)πr³. Using a radius (r) of 3 cm, we get V = (1/2)(4/3)π(3 cm)³.
Let's calculate the volume step by step:
Therefore, the approximate volume of the hemisphere is 56.6 cm³, when rounded to the nearest tenth of a cubic centimeter.
Answer:
$40.00
Step-by-step explanation:
Kevin has in a savings account = $1,427
His brother Haley has saved in the month with a 4 that is 1/10 the value of the 4.
The value of the 4 in 1,427 is at hundredth place = 4 × 100
and 1/10 of 400 = 40
Therefore, Haley have $40.00 in his savings account.
Answer:
The distance between home and river is 2 miles. In still water a boat can cover 18 miles in 3 hours.
Unit rate of the boat is calculated as
Unit rate of the boat is 6 miles per hour.
In the morning, a fisher man walks towards river and sits on the boat and moves in still water, then total distance covered by the fisher man is defined by the equation
400 because another way to find one tenth of something is to divide by 10 so you would simply do 4,000 divided by 10 to get 400. HOPE I HELPED!!!
