Answer:75,
Step-by-step explanation:
1/2 bh= A for one T 5*5=25 25*6= 150
150/2=75
OR
5*5/2=12.5
12.5*6=75
Answer:
1. ![Area = 28.26](https://tex.z-dn.net/?f=Area%20%3D%2028.26)
2 and 3: See explanation
Step-by-step explanation:
Solving (1)
--- radius
The area is:
![Area = \pi r^2](https://tex.z-dn.net/?f=Area%20%3D%20%5Cpi%20r%5E2)
![Area = 3.14* 3^2](https://tex.z-dn.net/?f=Area%20%3D%203.14%2A%203%5E2)
![Area = 28.26](https://tex.z-dn.net/?f=Area%20%3D%2028.26)
There are no enough information to solve (2) and (3) as the radius and/or diameter are not provided.
However, the following formula will be used to calculate the required areas.

Answer: 22 blue balloons
Step-by-step explanation:
IF 3/10 balloons are red out of 60, we have
