The cost would be at least $755.1302 to build the deck.
The deck is in the shape of a rectangle. Therefore,
<h3>Area of rectangle</h3>
where
l = length
w = width
length = 9.4 ft
width = 6.7 ft
area = 9.4 × 6.7 = 62.98 ft²
Therefore,
1 ft² of lumber = $11.99
62.98 ft² of lumber = ?
cross multiply
cost = 62.98 × 11.99 = $755.1302

Answer:
7y^2 +8xy -3
Step-by-step explanation:
Distribute the minus sign and combine like terms.
= 7y^2 +6xy +2xy -3
= 7y^2 +8xy -3
A.
volume of a sphere is 4/3*pi*r^3
4/3*3.14*1.6^3 = 17.1486 cm^3
because it is a half sphere, divide that by 2:
8.5743 cm^3
b.
volume of a cylinder is base area (pi * r^2) multiplied by the height
The cylinder shares a radius with the half sphere, so this gives us:
3.14*1.6^2*6.2 = 49.8381 cm^3
c.
this is simply the combined volume
8.5743 + 49.8381 = 58.4124 cm^3
