Answer:
112.5ft^2
Step-by-step explanation:
10 x 9 = 90
9 × 5 × .5 = 22.5
90 + 22.5 = 112.5
Place the right angle at the origin. Short leg on x-axis.
The forth corner of the square is the point on the hypotenuse where the line y = x intersects. (Draw a diagram!)
In this case the hypotenuse is y = -4x/3 + 8
x = -4x/3 + 8
7x/3 = 8
7x = 24
x = 3.428571429
Answer:
D.
Step-by-step explanation:
Answer:
676 cubic cm choice d
Step-by-step explanation:
Base area times height gets volume
Base area = (1/2)*13 * 8 = 52 sq. cm (area of the right triangle)
height = 13 cm here
Volume = 13 cm * 52 sq. cm = 676 cubic cm
Answer:
105.12 ft²
Step-by-step explanation:
Let's first find the area of the rectangle.
ft², so the rectangle has an area of 80ft².
To find the area of the semi-circle, we find the area of a whole circle and divide by two.
The formula to find the area of a circle is 
. The radius is 4, as the diameter is 8.
Add 80 and 25.12:
