Is there a picture that goes with the problem
The formula for finding the area of a circle is
a = pi × radius^2
Since the diameter is 14 inches, the radius is 7 inches, so to solve...
a = pi × 7^2
a = 3.14 × 49
a = 153.86
Rounded to the nearest tenth...
153.9 inches^2

Answer:
whenever you're multiplying terms that have exponents you multiply the coefficients and add their exponents:
Step-by-step explanation:
I think the answer to your first question should be:
30a²b - 30ab²
Your second answer is good
whenever you're multiplying terms that have exponents you multiply the coefficients and add their exponents:
for example, 6a²b³c x 2abc = 6(2)(a²)(a)(b³)(b)(c)(c)
= 12a³b⁴c²
