Answer:
1/2
Step-by-step explanation:
=[-1/4 + 1/6] ÷ [1/3 - 1/2]
=[-3/12 + 2/12] ÷ [2/6 - 3/6]
=[-1/12] ÷ [-1/6]
=[-1/12] x [-6/1]
= 1/2
Answer:
A=195.97 cm^2
Step-by-step explanation:
Area of a circle is given by
A = pi r^2
We are given the diameter. We need to find the radius
d= 2r
15.8 = 2r
Divide by 2
7.9 =r
Now we can find the area
A = pi * (7.9)^2
A = pi *62.41
Let pi = 3.14
A = (3.14) * 62.41
= 195.9674 cm^2
We round to the nearest hundredths
A=195.97 cm^2
