I think it is 12 yds^2. Area of a triangle is base*height / 2, which would be (8 * 3) / 2.
Answer:
42.84 cm
Step-by-step explanation:
It would be easiest to split this first. To find the circumference of a circle, it is 2πr.
d= 12
r= 6
C= 2π6
C= 12π
Divide by 2 because you are only trying to get the circumference of half the circle.
C= 6π
Now you can add all the other sides to find the total perimeter.
P= 6(3.14) + 10 + 6 + 8
P= 42.84 cm
Answer:

Step-by-step explanation:

To add the two fractions, you need a common denominator. In this case, the lowest common denominator (LCD) is 9y. That's because 9y is divisible by both 3y and 9y.
The first fraction must be changed so that its denominator is 9y. Do this by multiplying both numerator and denominator by 3.

Finally, this answer can be simplified ("reduced") by dividing both numerator and denominator by 3, their greatest common factor.
A^2 + b^2 = c^2
7^2 + 4^2 = 65
square root of 65 is 8.06
answer: 8.06
