Step-by-step explanation:
you just have to add the oak to pine and pine to end then you subtract the total of maple to end.
153.8 = 3.14r^2
Divide each side by 3.14 to get r alone.

r = 6.999
r= 7
Answer:
The correct answer is,
the area of given triangle = 1875 square feet
Step-by-step explanation:
Formula:
Area of triangle = bh/2
b - Base and h - height
It is given that,a triangle with a base of 50 feet and a height of 75 feet’
<u>To find the area of triangle</u>
base b = 50 feet and height h = 75 feet
Area = bh/2 = (50 x 75 )/2
Area = 3750/2 = 1875 square feet
Therefore the area of given triangle = 1875 square feet
