Answer:
area of pool = w(w+5) = w^2 + 5w square feet
Explanation:
The height of the pool is used as its width.
Assume that the width of the pool is w feet.
Now, we are given that the length of the pool is 5 feet longer than its width.
This means that:
length of the pool = w + 5 feet
The area of the rectangle is calculated as follows:
area = length * width
area = (w+5) * (w)
area = w^2 + 5w square feet

Answer:
Step-by-step explanation:
We have the cone and the half-sphere.
The formula of a volume of a cone:
r - radius
H - height
We have r = 7cm and H = (22-7)cm=15cm. Substitute:
The formula of a volume of a sphere:
R - radius
Therefore the formula of a volume of a half-sphere:
We have R = 7cm. Substitute:
The volume of the given shape:
Substitute:
You write 10+4+.05.
this is because you add each value separately <span />
