Answer:
about 13.73 square feet
Step-by-step explanation:
We presume you want the area of the figure.
It can be decomposed into a triangle with base 3.6 ft and height 4.8 ft, together with a semicircle of diameter 3.6 ft.
The area of the triangle is given by ...
A = 1/2bh
For the given base and height, this is ...
A = (1/2)(3.6 ft)(4.8 ft) = 8.64 ft²
__
The radius is half the diameter, so the radius of the semicircle is 1.8 ft. The area of a whole circle of radius 1.8 ft is given by ...
A = πr² = π(1.8 ft)² = 3.24π ft²
We want the area of half the circle, so its area will be ...
semicircle area = (1/2)(3.24π ft²) = 1.62π ft² ≈ 5.089 ft²
__
Then the total area of the figure is ...
total area = triangle area + semicircle area
= 8.64 ft² + 5.09 ft²
total area = 13.73 ft²
<h3>
The coordinates of the point A is (3,5).</h3>
Step-by-step explanation:
Here, given the line segment is AC.
Let us assume the coordinates of the point A = (p,q)
The point M (0,5.5) is the mid point of line segment AC.
By<u> Mid-Point Formula:</u>
The coordinates of the mid point M of segment AC is given as:
So, the coordinates of the point A is (3,5)
There is a total of 31 marine lives in the fish tank. The probability of picking a goldfish is 24/31 since there are 24 goldfish. Further, the probability of picking an angel fish is 2/31 as there are 2 angel fish in the tank. The final probability is the sum of the two probabilities,
P = (24/31 + 2/31) = 26/31
The answer is 26/31.
