The problem did not state if the 1cm measure is the radius or diameter.
Area of a circle = π r²
Assuming: 1 cm is the radius
Area of 1 button = 3.14 * (1cm)² = 3.14cm²
Total area = 3.14cm² * 7 buttons = 21.98 cm²
Assuming: 1cm is the diameter : radius is 1/2 = 0.50cm
Area of 1 button = 3.14 * (1/2cm)² = 3.14 * 0.25cm² = 0.785cm²
Total area = 0.785cm² * 7 buttons = 5.495cm²
Answer:
volume of the prism 5cm
Step-by-step explanation:
Answer:
47
Step-by-step explanation:
sinice they are similar they have the same angles so 180-118-15=f
so f=47
I'd go with Checking account B because its cheaper .
Answer:
(3, 10)
Step-by-step explanation:
f(3) means substitute the value of x = 3 into f(x)

Therefore, when x = 3, y = 10
So the ordered pair is (3, 10)
