Circumference of a circle:
C = 2 pi r
r = C / 2 pi
r = 37.68 / (2 * 3.14)
r = 6
Area of a circle:
A = pi r^2
A = 3.14 * 6^2
A = 113.04
Answer
The area of a circle = 113.04 square units
(6,0) this is right because translation is j moving a figure while dilation means multiply each x and y by scale factor
Answer:
Microsoft, 1998. "The "12-inch" ball measures between 11.88 and 12.13 in (30.2 and 30.8 cm) in circumference and weighs between 6.25 and 7 oz (177.2 and 198.4 g)." Softball. ... Weight not less than 6 1/4 ounces or more than 7 ounces."
Step-by-step explanation:
Setup
0.8x + 0.4y = 50
0.1x + 0.2y = 10 - Multiply by -2 and add
get
0.6x = 30
x = 50 mg compound A
.1 (50) + .2y = 10
5 + .2y = 10
.2y = 5
y = 25 mg compound B
