Answer:
A = 81π cm²
Step-by-step explanation:
The formula for area of a circle is A = πr², where r is the radius. The radius is half the diameter, so our radius for this problem is
18/2 = 9. So the area is..
A = π(9²) = π(81)
A = 81π cm²
Answer:
X = 3
Step-by-step explanation:
first you would do 2 * 5x - 2 * 7 = 2x+10
second you'll get 10x- 14 = 2x + 10
third subtract the 2x by the 10x
fourth you'll get 8x
fifth then add the 14 to the 10
sixth 8x = 24
divide that by 8x to both sides
so then you get x=3
Since 12.3 is kind of a margin that you have to fit by, the total weight of the golf clubs must be lesser than or equal to 12.3. So, that's your expression:
x represents the number of golf clubs you have.

Answer:
x=11
Step-by-step explanation:
Vertical angles are congruent, so m∠A = m∠B.
4x+8 = 5x-3
Subtract 5x from both sides.
-1x+8=-3
Subtract 8 from both sides to isolate the variable.
-1x=-11
Divide both sides by -1 to solve for x.
x=11
Plug in 11 for x into m∠A=(4x+8)=(4(11)+8)=(44+8)=52.
Answer:
yeah, it's A your correct!
hope it helps;)
