Find the surface area in terms of π

Question 3 options:

32 m2

64 m2

80 m2

96 m2

96π²

Step-by-step explanation:

SA = 2 π²+πdh

SA = 2π4²+πdh

SA = 2π4²+π8*8

SA = 2π16+π64

SA = 32π+64π

SA = 96π²

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
