Answer: 44.5 ft²
Step-by-step explanation:
The area of pink blanket is considering A=5\times 5.7=28.5 and the area of a rectangle is A=l\times w
.
Now we have area of the pink blanket which is 28.5.
The area of blue blanket - A=24=6 x 4
Area of a triangle: A= 1/2 x base x height and that is 1/2 x 4 x 4 which is 8. and that is the area of both blankets.
Now, pink blanket 28.5 x blue blanket 24 minus 8 is giving us the number that is referring to total area that is covered and that is 44.5 ft²
Answer:
The lateral area is
Step-by-step explanation:
we know that
The lateral area of a right prism is equal to
where
P is the perimeter of the base of the prism
H is the height of the prism
in this problem we have
substitute
5.32 x 1.9 equals <span>10.108
</span>i cant explain but that is the answer
Answer:
Semicircle radius is 4.5
Radius x radius x 3.14 = area of circle but you divide by 2
4.5 x 4.5 = 20.25 x 3.14 = 63.585/2=31.7925 for semicircle
To find the line for the triangle subtract 16 from the other side which is 8 so the triangle is 8 by 3.
8 x 3 = 24/2=12 for triangle
6 + 3 = 9 the missing side.
9 x 8 = 72 so the rectangle is 72
72 + 12 = 84 + 31.7925 = 115.7925 so that is the area
Circumference is the perimeter for the circle. 9 x 3.14 = 28.26
Perimeter of triangle is 19.544
8 + 9 = 17 x 2 = 34
28.26 + 34 = 62.26 + 19.544 = 81.804
Area is 115.7925 and perimeter is 81.804
