The base is 315. Perimeter of base is 72.
So it work like this
180-72= 108
x+4=108
x=108-4
x=104
The surface area of a sphere of radius r is A = 4π*r^3.
Since the radius in this case is 8 cm (half the 17 cm diameter), the area of this sphere is
A = 4π(8 cm)^2, or 256π cm^2.
Answer:
35
Step-by-step explanation:
Given f(x) = x⁴ – 3x³ + x – 3. What is Limit of f (x) as x approaches negative 2?
=> f(-2) = (-2)⁴-3(-2)³+(-2)-3
= 16+24-2-3
= 35
She is not correct because the absolute value of -2 is 2 and the absolute value of 2 is 2
