Answer:
1040 cm^2
Step-by-step explanation:
If you separate the T into 2 rectangles, you can calculate the are of each one. (First one is 20*4 which equals 80, Second one is 16*60 which equals 960)
Then find the sum, 960+80=1040cm^2
cm^2 because it’s an area (2 dimensions)
Answer:
2.2
Step-by-step explanation:
To find a, you use a formula called the law of cosines:
The law of cosines tells us:
a^2 = b^2 + c^2 - 2bc cosA
So lets plug in the values:
a^2 = 4^2 + 3^2 -2(4)(3)cos(32)
a^2 = 25-24cos32
a^2 is roughly equal to 4.97
therefore a roughly equal to 2.2
Answer:
It would be Square root of 38, and square root of 44 because they are all between 5 and 10. I'm sure you don't need their exact values, but that's them.
If you have nay more questions let me know! :)
Diameter is 13
radius is 6.5
circumference is 13pi or 40.84
area is 42.25pi or 132.732
