Answer:
1) Radius of the cone = 9.5 cm
2) BA = 90.25 π cm²
3) SA = 384.7 π cm²
Step-by-step explanation:
1) Radius of the cone = 9.5 cm
2) Base Area of the cone = 
BA = (π)(9.5)²
BA = 90.25 π cm²
3) Surface Area of Cone = 
SA = π(9.5)(9.5 + √(29.5)²+(9.5)²)
SA = 9.5π(9.5 + 31)
SA = 9.5π(40.5)
SA = 384.7 π cm²
In this item, we are already given that the length of the rectangular book can be represented by the variable x. In this way, the width, which was described to be the difference of the length and 3 inches, can be expressed as x - 3.
The area of the triangle is rectangle is calculated by multiplying the length, x, and the width, which was derived to be x - 3.
Area = Length x width
Area = (x)( x - 3)
Putting in the value of the area, we have the final answer as,
x(x - 3) = 63.8 in²
Hence, the final answer is the first answer.
28% = 28/100 = 0.28
$100.80/0.28 = $360 ← answer
So it starts by 22.50 regularly so she worked 40 regular hours so $22.50 * 40h= $900 and in over time she gets double for working over time so $22.50 * 2 = $45 and she worked 12 hours so 12h * $45 = $540 then we need to add those two numbers up 900 + $540 = $1,440 is our answer/outcome.
