Area = pi * r^2
A = 3.14 * 7.6^2
A = 181.37

In short, Your Answer would be 181.37 cm^2

Hope this helps!

To find the area the formule is pi(r^2) pi(radius times radius)
3.1416 (7.6(7.6)) = <span> 181.458816

Answer=13 feet long

This information describes a right triangle, with sides 5ft and 12ft.

a²+b²=c²
5²+12²=c²
25+144=c²
169=c²
√169=√c²
13=c

The ladder needs to be 13ft long

36. GEOMETRY Write an algebraic expression to

Stels [109]

Answer:

108 in²

Step-by-step explanation:

Area of a triangle is given as ½*base*height

The base of the given triangle = h + 6

height = h

Algebraic expression for its area = $\frac{1}{2}*(h + 6)*h = \frac{1}{2}(h^2 + 6h) = \frac{h^2 + 6h}{2}$

Evaluate the area if h is given as 12 inches.

Plug in the value of h into the algebraic expression:

$\frac{h^2 + 6h}{2} = \frac{12^2 + 6(12)}{2}$

$= \frac{144 + 72}{2}$

$= \frac{216}{2} = 108 in^2$
