Question

If the length of an arc and radius of a sector are 28cm and 14cm then the area of sector is

a. 196cm²
b.194cm²
c.176cm²
d.184cm2​

Answer 1

Answer:

a. 196cm²

Step-by-step explanation:

to make it understand i am doing it the basic way

since the radius is 14cm

SO,

circumference will be

2π = 28―

and area will be

П^2 = 196П

so if 281 of arc length give 196― of area

then 28cm of arc length will give area of

let x

28π/28 = 196T/X

x = 196 sq. cm

hope it helps
