Answer:
$80.59
Step-by-step explanation:
You add the price of the raincoat and shoes to get 152.75, you then subtract the price of the 4 shirts you returned to get 76.75. The 5% tax for this is 3.84 so you add the two together and you get $80.59.
V=(4/3)pir^3
SA=4pir^2
so
V=288=(4/3)pir^3
times both sides by 3/4
216=pir^3
divide both sides by pi
216/pi=r^3
cube root both sides
6/(∛pi)=r
sub into other
sa=4pir^2
sa=4pi(6/(∛pi))^2
SA=4pi(36/(∛(pi²)))
SA=144pi/(∛(pi²))
SA=144pi∛pi/pi
SA=144∛pi
SA≈210.901 in²

Step-by-step explanation:
Answer:
(x + 3)² + (y - 4)² = 32
Step-by-step explanation:
Since we are given the coordinates of the centre and a point on the circle, we can use distance formula to find the radius.
r = √((1 - (-3))² + (8 - 4)²)
r = √(16 + 16)
r = √32
Now, formula for equation of a circle with centre (h, k) is;
(x - h)² + (y - k)² = r²
Our centre is (-3, 4) with r = √32
Thus;
(x - (-3))² + (y - 4)² = (√32)²
(x + 3)² + (y - 4)² = 32
