For the one you put in the comment...
The radius of a circle is 19cm find its area in terms of π
A = π
A = π 1
A = 361π
For the other one you put in the comment
The radius of a circle is 4 cm find its area in terms of π
A = π
A = π
A = 16π
For the other one you put in the comment
The radius of a circle is 20 cm find its area in terms of π
A = π
A = π
A = 400π

Answer:
- 63 ft²
- h = 2A/b; h = 7 ft
Step-by-step explanation:
1. Put the values where the variables are in the formula, then do the arithmetic.
... A = (1/2)bh = (1/2)(18 ft)(7 ft) = 63 ft²
2. Divide by the coefficient of h. Substitute the given values and do the arithmetic.
... A = (1/2)bh
The coefficient of h is b/2, so we divide by that—or multiply by its inverse, 2/b.
... 2A/b = h
Substituting the given numbers, you have ...
... 2(28 ft²)/(8 ft) = h = 7 ft
The height of the triangle is 7 ft.
