Answer:

6

Step-by-step explanation:

Recall the area of a triangle formula

A=\frac{bh}{2} where b = base and h = height

The triangle shown has a height of 4cm and a base length 3cm

Using this information we plug in the values into the formula

A=\frac{4*3}{2} \\4*3=12\\\frac{12}{2} =6

Hence, the area of the triangle is 6 square centimeters

Find the center and radius of (x + 9)^2 + (y + 6)^2 = 9.
VARVARA [1.3K]
You can do this by comparing your equation to the general form of equation of a circle

( x - a)^2 + (y - b)^2 = r^2       where (a,b) is the centre and r = radius:-
(x  + 9)^2   (y + 6)^2 = 9 

so (a,b) = (-9,-6)  and r = 3

so the answer is B
