Since the diameter is 12cm, we will use the radius formula = d/2= r
12/2 = 6cm
Area:
A = 3.14(r)^2
A = 3.14(6)^2
A = 3.14(36)
Answer:
A= 113.04 sq cm
Answer:
16, see below :)
Step-by-step explanation:
Hello!
We can use the pythagorean theorem because one of the angles is 90 degrees. According to the theorem, a^2 + b^2 = c^2
a is 12, b is unknown, and c is 20
Now we use the theorem
12^2 + b^2 = 20^2
144 + b^2 = 400
b^2 = 256
b = sqrt(256)
b = 16

Answer:
5.6
Step-by-step explanation:
2.4 / 3 = x / 7

Answer: 37 fruit pies+42 fruit juices=79 total items
(a) 37*1.65= $61.05
42*1.36= $57.12
(b) Mr Sanchez's class earned more money.
(c) Mr. Sanchez's class earned $3.93 more than Mr. Kelly's class
$61.05-$57.12= $3.93
