I think it’s A. 12mm Bc if u take away 4mm from the 10mm it gives u the triangles base which is 6mm and then taking away 8mm from 12mm gives u 4mm which would be the height
To find the area of a triangle u need the base and height
Triangle Area= 1/2bh
1/2(4)(6)= 12
Answer:

Step-by-step explanation:
We can use properties of exponents to solve these equations. Remember that when multiplying exponents, we 'add' them.

For the next question:

These are your answers!
Answer:
power of 10 is the number 10 multiplied by itself by the number of times indicated by the exponent. Thus, shown in long form, a power of 10 is the number 1 followed by n zeros, where n is the exponent and is greater than 0; for example, 106 is written 1,000,000.
Step-
Ok....?
The diameter is 6, the radius is 3 and the Area is 9pi
I believe the answer is the last one. I hope this helps love! :)
