Question

can someone explain the steps to this?

Answer 1

Use the formula for finding the area of a sector
\[\Large A=\frac{\Theta}{360} * \pi * r^2\]

The radius is just half of the diameter, 4
and theta, the angle, is just 180

\[\Large A= \frac{180}{360} * \pi *(4)^2 \]

Answer 2

hi ! than the diameter is 8 m so in this case the length of the radius is equal how many ?

Answer 3

hi jhony
i think i mightve gotten it

A=πr^2
A=π(4)^2
A=π(16)
A=50.27/2
A=25.1

Answer 4

yes you are right with this just dont forgat the unit measure of area

Answer 5

questions ?

Answer 6

oh right
25.1 m^2

Answer 7

exactly
