Answer:
63.0
Step-by-step explanation:
area of circle = πr²
area of quarter circle = πr²/4
area of triangle = bh/2
area of shaded quarter circle:
πr²/4 = (3.14159)(7²)/4 = 38.4845 units²
area of shaded triangle:
bh/2 = (7)(7)/2 = 24.5 units²
total shaded area = 38.4845 units² + 24.5 units² = 62.9845 units²
Answer: 63.0 units²
An art gallery is a 6-story square pyramid with base area of half an acre. Estimate the volume in cubic yards of the art gallery. In your calculations, use 1 acre = 4840 yd2 and 1 story = 10 ft.
In order to find out what the blank of your expression is,, we must solve for y. We can start doing this by distributing -2 through the parenthesis.
y - 4 = -2x - 6
Now you need to move the constant to the right side and change its sign.
y = -2x - 6 + 4
Calculate the sum of -6 + 4.
y = -2x - 2
Since we cannot simplify this down any further,, y is going to equal -2x - 2.
Let me know if you have any further questions.
