We are solving for the area of a circle, the formula to solve for the area of a circle is A=pi*r^2. The radius is half of the diameter given, so the radius would be 9.
A=pi*r^2 Substitute 9 for r
A=pi*9^2 Solve the power
A=pi*81
A=254.34
The answer is G or 254 square feet.
Answer:
x = 12, so PTQ = 40 deg
Step-by-step explanation:
first, because the two are vertically opposite, they are equal, write a formula for this:
x + 28 = 2x + 16 (minus 2x from both sides)
-1x + 28 = 16 (minus 28 from both sides)
-1x = -12 (divide both sides by -1)
x = 12
sub into formula:
12 + 28 = 40

Answer:
p = 48
Step-by-step explanation:
If p is inversely proportional to the square of q
This is written Mathematically as:
p ∝ 1/q²
p = k × 1/q²
p = k/q²
Cross Multiply
k = pq²
k = Constant of Proportionality
Step 1
We find k
When p is 3 when q was 12
k = pq²
k = 3 × 12²
k = 432
Step 3
determine p when q is equal to 3
p = k/q²
p = 432/3²
p = 48
