-- When the man at the North end throws the ball, the canoe
accelerates to the North.
-- While the ball is in flight, traveling south by the length of the
canoe, the canoe moves northward at a constant speed.
-- If the man at the south end misses the ball and fails to catch it,
then the canoe continues moving south at a constant speed, even
after the ball has passed him.
-- If the man at the south end successfully catches the ball, then the
canoe accelerates south at that moment, and comes to rest in the water.
This question is in two parts. This is not the correct multiple choice options for this part a.
The second part had the option
b)If your bedroom has a circular shape, and its diameter measured 6.32 , which of the following numbers would be the most precise value for its area?
a)30 m^2
b) 31.4 m^2
c)31.37 m^2
d)31.371 m^2
Answer:
A. 17.0 m²
B. 31.4 m²
Explanation:
The formula for the calculation of the area of a rectangle is given as
Area = length x width
The length = 3.547 m
The width = 4.79 m
Then area = 3.547 x 4.79
= 16.990m²
When approximated = 17.0m²
This is the most precise measurement for the area of the bedroom.
B.
We solve b using this formula
Area = pi(diameter/2)^2
= 3.14(6.32/2)²
= 3.14 x 9.9856
= 31.4 m²
