The area of the circle is 28 ft square.
The area of the triangle is 30 ft square.
Step-by-step explanation:
1) The area of the circle= π*r^2
where π= 3.14(default value) and "r" is the radius of the circle.
Here, Radius of the circle(r)= 3 ft
Area = 3.14*3*3
= 28.26 ft sq.= 28 ft sq(rounded to the nearest whole number)
2) The triangle has the base= 10 feet and height= 6 feet
The Area of the triangle= 1/2(b)(h)
where "b" is the base and "h" is the height of the triangle.
Substitute b=10 and h=6 ,
Area of triangle= 1/2(10 ft)(6 ft)= 60/2= 30 feet sq.
First. You have to look at what kind of proportionality it is.It is an Inverse Proportion.so you see the rate of change is 2.3
Easy, 100 x 3 is 300 pounds, 5 x 3 is 15, so 15 pounds. :)
If you can use a calculator, enter (4/1/4)/(4/1/2) and you will get 1/2
