Answer is 80pi
Step by step

To find lateral_area = (2 * π * r) * h

Since it’s in term of pi,
(2 x radius x height) pi
2 x 4 x 6 = 48pi

base_area = 2 * π * r²
Since it’s in terms of pi
(2 x r^2)
(2 x 4^2)
= 32pi

Total surface area in terms of pi = 32+48
= 80pi

Divide and simplify ax + ay + bx + by/ x+y

Kisachek [45]

Answer:

a + b

Step-by-step explanation:

ax + ay + bx + by

a(x +y) +b(x + y)

(a + b) ( x + y)

therefore (a + b) ( x + y) divide x+y

x + y is canceled out both in the denominator and numerator

= a+b
