PLEASE ANSWER!!!!!!
The semicircle below has a diameter of 20. Find the area of the blue region.
Answer:
61
Step-by-step explanation:
Use the area of semicircle minus the area of the triangle. Area of the semicircle is 10^2 * pi / 2 = 50 pi, the area of the triangle is 12*16/ 2 = 96. The the area for the blue part is 50 pi - 96 = 61.07963268 or 61.
If it is helpful, plz give me Brainliest.
Answer:
50pi - 96
Step-by-step explanation:
The radius of the semicircle is 10, so the area of the entire semicircle is 1.2*10^2 pi = 50pi
The white triangle has an area of 1/2*12*16 = 96 so subtracting it shows that the blue area is 50pi-96
Answer part A and Part B
Answer:
first one is 20 and second is 21
Step-by-step explanation:
7/(1/3)
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
7 x 3 1
=
21 1
Thus, the answer to 7 divided by 1/3 in fraction form is:
21 1
To make the answer to 7 divided by 1/3 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
21 / 1 = 21
The answer is rounded to the nearest two decimal points if necessary.
21/1 is an improper fraction and should be written as 21.
for the
now the first one 4/(1/5) is 20 becaue...
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
4 x 5 1
=
20 1
Thus, the answer to 4 divided by 1/5 in fraction form is:
20 1
To make the answer to 4 divided by 1/5 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
20 / 1 = 20
The answer is rounded to the nearest two decimal points if necessary.
20/1 is an improper fraction and should be written as 20.

The square prism has a base length of 2 ft. Which describes the cross-section of the prism that is perpendicular to the base?
a rectangle with two 12-ft sides and two 2-ft sides
a rectangle with two 12-ft sides and two sides that are shorter than 2 ft
a non-rectangular parallelogram with two 12-ft sides and two 2-ft sides
a non-rectangular parallelogram with two 12-ft sides and two sides that are longer than 2 ft
The option that describes the cross-section of the prism that is perpendicular to the base is A. a rectangle with two 12-ft sides and two 2-ft sides.
How to explain the rectangleA square prism has a square base. When we cut a prism perpendicular to the base, we get a cross-section that is a rectangle with the same dimensions as the base. In this case, the base of the prism is a square with a side length of 2 ft, so the cross-section will be a rectangle with two 12-ft sides and two 2-ft sides.
The other answer choices are incorrect. A rectangle with two 12-ft sides and two sides that are shorter than 2 ft is not possible. A non-rectangular parallelogram with two 12-ft sides and two 2-ft sides is not a cross-section of a square prism. A non-rectangular parallelogram with two 12-ft sides and two sides that are longer than 2 ft is not a cross-section of a square prism, because the sides of a square prism are all the same length.

Answer:
65°
Step-by-step explanation:
the angle of a straight line has to add up to 180°
if it doesn't, it's not a straight line
115° and x are supplementary angles
meaning we know they have to add up to 180°
so simply subtract
180- 115 =
65°
you can check work by adding
115+65= 180
Answer: 65
180-115=65
Step-by-step explanation:
A straight line is always 180 so I subtracted 115 from 180.
