Answer:
The area of the deck that surrounds the hot tub is 17.9 m².
Step-by-step explanation:Base of deck = 5 m
Height of deck = 5 m
Area of deck = base*height
= 5*5
= 25 m²
A circular hot tub is placed in the deck whose diameter is 3 m.
Radius = diameter/2
= 1.5 m
Area of the circular hot tub = πr²
= 3.14*(1.5*1.5)
= 7.07 m²
Area of the deck that surrounds the hot tub = Area of deck - Area of tub
= 25 - 7.07
= 17.93 m²
= 17.9 m²
The answer will be 1/2 because in a coin there is heads and tails. So, its 50% chance to get either one. Now, for 2 coins there will be heads, tails, head, and tails. The question ask you for tails so there are 2 ways to get tails. Also, the total of the two coins to get either heads or tail is 4. You should get 2/4 which is 1/2.
