Answer:
13.) 0.19625 15.) 37.68
Step-by-step explanation:
Formula for area of a circle: A=πr²
13.) 3.14 x .25² = 0.19625
Formula for circumference for a circle: C=πD or C=2πr
15.) (6 x 2) x 3.14 = 37.68
Hope this helped : )
I think it’s (3,-2) not 100 percent but if ur rotating counterclockwise the x should be positive and the y negative... I think
Answer:
w = 10 cm
Step-by-step explanation:
The area (A) of the triangle is calculated as
A =
base × height
here base = 6 and height = 8, thus
A = 0.5 × 6 × 8 = 3 × 8 = 24 cm²
The area of the rectangle = 5 × 24 = 120 cm²
area of rectangle = lw ( l is length, w is width )
Here l = 12, thus
120 = 12w ( divide both sides by 12 )
w = 10 cm

Answer:the library checks out 2 times more fiction books than the nonfiction books.
Step-by-step explanation:
Total number of fiction books that the Library checks out in an hour is 4.
Total number of non fiction books that the Library checks out in an hour is 2.
To determine how many times more fiction books that they check out than the nonfiction books, we would divide the total number of fiction books that the Library checks out in an hour by the total number of non fiction books that the Library checks out in an hour. It becomes
4/2 = 2
