Answer:

967.6cm^{2}  (1 d.p)

Step-by-step explanation:

Total Surface Area of Cylinder = 2\pi rh+2\pi r^{2}

Given from the question, r = 7 cm and h = 15cm

Lets Substitute r and h into the formula to find the Total Surface Area of the cylinder.

Total Surface Area of Cylinder = 2\pi (7)(15)+2\pi (7)^{2} \\=210\pi +98\pi \\=308\pi cm^{2} \\=967.6cm^{2}  (1 d.p)

AB^2 + BC^2 = AC^2
AB^2 + 6^2 = square root 117^2
AB^2 + 36 = 117

Now subtract 117 from both sides
AB^2 = 81
AB = square root 81 = 9
\sqrt{81}  = 9
Therefore AB is 9 cms.

2. Write the equation of the circle in general form
Anon25 [30]
(-1,-2) and (-1,4)
so these have same x values, but different y values, so these are on differnt sidef of circle

distanc between them is 6
6/2=3
radius=3

so move 3 units up from (-1,-2)
(-1,1)
so

if center is (h,k) and radius is r then
(x-h)^2+(y-k)^2=r^2

(-1,1) is center and r=3

(x-(-1))^2+(y-1)^2=3^2
(x+1)^2+(y-1)^2=9
