The first triangle’s area is 48.75. But since you round it to the nearest tenth, it’s 48.7.
Use the formula a=1/2bh to find the area of a triangle.
A= 1/2• 13 • 7.5
A= 6.5• 7.5
A= 48.75 —-> 48.7 square inches.
Sorry, I can only do one because of homework, but make sure to use that formula! Hope this helped.
Hi there!
The formula for the circumference of a circle is C = pi x D or C = 2 x pi x r. This means that the circumference is equal to either pi times the diameter or twice the radius.
Hope this helps!! :)

Answer:
c = 36
Step-by-step explanation:
Given
a² + 12a + c
To complete the square
add ( half the coefficient of the a- term )² to a² + 12a
a² + 2(6)a + 6²
= (a + 6)² + 36
Hence the value of c = 36
