Find the surface area of the cylinder to the nearest tenth of a square unit. use 3.14 for pi

Alborosie

Given:

Height of cylinder is 18.2 cm
Radius of cylinder is 3 cm

$~$

To Find?

Surface area

$~$

Solution:

Using formula:

Surface area of cylinder = 2πr (h + r)

$~$

Substituting values in the formula:

$\longrightarrow \sf 2 × 3.14 × 3 (18.2 + 3)$

$\longrightarrow \sf 6.28 × 3 (21.2)$

$\longrightarrow \sf 18.84 × 21.2$

$\longrightarrow \sf 399.4 cm²$

$~$

Hence, (B) 399.4 cm² is right answer.

Write an equation for the line that connects A (-4,8) and B (6,3)

Mazyrski [523]

Answer:

7y+5x=76

Step-by-step explan

A (-4,8) and B (6,3)

First find the slope;

m= (y2-y1)/(x2-x1)

m=(3-8)/(3+4)

m=-5/7

now using equation of line

y-y1= m(x-x1)

y-8=-5/7 (x+4)

y-8=(-5x+20)/7

7(y-8)= -5x+20

7y-56=-5x+20

7y+5x=20+56

7y+5x=76
