Answer:
The answer is D, 43
Step-by-step explanation:
If the pile gets bigger by 8 each week, and you want to find out how big the pile is after 3 weeks, then you have to multiply 8
by 3 to find out how much the pile increased by.
8 × 3 = 25
Now, you need to add this to your initial value to get the answer.
25 + 17
= 42
Now simplify.
43
Answer:
(x - 16)² + (y - 4)² = 8
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (16, 4) and r = 2, thus
(x - 16)² + (y - 4)² = (2 )², that is
(x - 16)² + (y - 4)² = 8
Answer:
144π
Step-by-step explanation:
The formula for finding the surface area of a sphere is 4π
Substitute 6 in for r. 4π = 144π
