Answer:

4

Step-by-step explanation:

Here you need not completely solve 7992 squared. You can just take the last digit which in this case is 2 and solve for the square of that digit. 2 x 2 = 4. Now if it was a bigger digit which would result in a two digit number when squared you would take the last digit of that number. But, we don't need to do that here since 2 squared is 4.

Answer:

54.5 $ft^{2}$

Step-by-step explanation:

divide it to one rectangle and two different triangles.

Rectangles area: (8+3)*4 = 44 $ft^{2}$

triangle top: 4*3/2 = 6 $ft^{2}$

triangle bottom: 3*3/2= 4.5 $ft^{2}$

sum the all up: 44+6+4.5 = 54.5 $ft^{2}$

What radius of a circle is required to inscribe an equilateral triangle with an area of 35.074 in2 and an altitude of 7.794 in?

levacccp [35]

Answer:

(C) r=5.2 in

Step-by-step explanation:

firstly, we will draw diagram

we know that

centroid divides altitude into 2:1 form

so, we get

$r=\frac{2}{3}\times h$

now, we can plug

h=7.794

$r=\frac{2}{3}\times 7.794$

$r=5.196in$

so, option-C...............Answer
