Step-by-step explanation:
In second 1, the distance that separates them is 80 cm
Then, in second 2, it is an additional 76 cm which is 156
then 72, etc. etc.
From that, we can continue adding until we the total sum is 420.
80+76+72+68+64+60=420
That's 6 seconds
Not the most elegant solution but I think one of the simplest.
Answer: V≈56.55
Step-by-step explanation:
V=πr2h
3 = radius
2=height
Fill in the formula = V=πr2h=π·32·2≈56.54867
<u>V≈56.55</u>
Answer: 14.465 (round if necessary)
Steps:
Area of a triangle: (0.5)(b)(h)
(0.5)(6)(6)
(0.5)(36) = 18
Area of a half circle: (2πr²)0.5
(2*π*1.5²)0.5
(7.07)0.5
= 3.535
18 - 3.535 = 14.465
