There are all parallelograms.
To find their area we need to use only one formula.
A=base*height
Everything is given, so
1) A=b*h=5.3*4=21.2 km²
2) A=b*h= 11*10.7= 117.7 mi²
3)  A=b*h= 10.5*7.9 =82.95 mi²

A club swimming pool is 21 ft wide and 33 ft long. the club members want an exposed aggregate border in a strip of uniform width
vovangra [49]
First compute the perimeter of the pool:
(21+33)*2=108 foot. 
Since the material cover 232 ft^2, then it is sufficient to divide the above number over the length of the border like this:
232/108=2.1

The trip can be 2.1 ft in wide.

Express the area A of a circle as a function of its​ radius, r. Determine the area of a circle whose radius is 11 inches. That​
nekit [7.7K]
<h2>Answer with explanation:</h2>

The function represents the area of a circle(A) is given by :-

A(r)=2\pi r

To determine the area of a circle whose radius is 11 inches. , we put the value of r=11 inches, we get

A(11)=2\pi (11)

Now, we put \pi=\dfrac{22}{7} in the above function , we get

A(11)=2(\dfrac{22}{7} )(11)\\\\\Rightarrow\ A=56.5714285714\approx56.57
