The answer is: C. approximately 1,519.76 square inches
the area of a circle with a radius of 22 is 1,520.5344 which leads you to answer C
The shape is already split into 3 different shapes, so you can find the area of each of those shapes and add them together.
Triangle 1 : 2 · 2 · .5 = 2 units²
Square : 2 · 2 = 4 units²
Triangle 2 : 4 · 2 · .5 = 4 units²
2 + 4 + 4 = 10 units²
Answer:
264 miles
Step-by-step explanation:
Let's convert 3 hours and 40 minutes into hours first.
Recall that 1 hour = 60 minutes.
Therefore 40 minutes = 40/60 hours = 2/3 hours.
The car travelled 3 and 2/3 hours in total.
Recall that distance = speed times time.
The car has travelled 72 x 3 2/3 miles = 264 miles.
Answer:
The sidewalk is 2 feet wide
Step-by-step explanation:
The area of the sidewalk is given as 80 square feet
The length and width of pool
including side walks will be;
10 + 2x and 6 + 2x
To get the area of the side walk
That will be area of total minus area of the pool
That will be ;
(10 + 2x)(6 + 2x) - 10(6) = 80
60 + 12x + 20x + 4x^2 - 60 = 80
4x^2 + 32x -80 = 0
x^2 + 8x -20
x^2 + 10x - 2x - 20 = 0
x(x + 10) -2(x + 10) = 0
(x-2)(x + 10) = 0
x = 2 or -10
since width cannot be negative;
The sidewalk is 2 feet wide
