Step-by-step explanation:
First, you need to find the area of the circle then times that by 14.
π Formula for the area of a circle
π r stands for radius, so you divide the diameter by 2 and get 7.
π49 This is the area of the circle
π49×14 Now multiply by 14
=686π This is your answer.
=2155.13256 When you times it by pi this is what you get
=2156 This is your answer if you want it rounded up

Step-by-step explanation:
Area of rectangle = 2.5 x 1 = 2.5
To get area of triangle we must use the altitude theorem to find the height:
let 'x' = altitude (or height)
x/1.5 = 2/x
cross-multiply to get:
x² = 3
x =
Area of triangle = 1/2(2.5)()
= 1.25 which is approx 2.12
Total area = 2.5 + 2.12 = 4.62
