What is the area of a circle if the radious is 4?

Answer 1

πr² = area of a circle

(π)(4²) = 16π = 50.27

Answer 2

Area of a circle = pi × r(squared)

where pi = 22/7
r - radius which in your case = 4
therefore your answer = 22/7 × 4 × 4 = 50.3 ( with your units suared, you didn't state what your unit of the radius was m or cm)

Answer 3

for a circle A=radious squared situations pi the section divided with the help of pi equals the radious squared then you definately basically discover the sq. root of the quantity you get pi=3.14 in case you probably did no longer understand :) so for fifty you do 50/pi then you definately take the quantity you get and discover the sq. root

Answer 4

Formula:
Area=pi x r ^2(squared)
Area equals pi multiplied by radius squared

A= pi x 4^2 (Area equals pi multiplied by 4 squared)
A= pi x 16 (Area eals pi multiplied by 16)
A= 16 pi or 50.26548246
A= 16pi or 50.3

Answer 5

Use this formula for finding
the area of a circle = πr²

= (3.1416) (4)²

= 50.26 unit.

Answer 6

Area = pi*r^2
pi = 3,1415926 (approximately)
r = 4 => r^2 = 16
Area = 3,1415926 * 16
Area = 50,2654816

Answer 7

the area of any circle can be given by the formula

πr² sq. units where r is the radius of the circle
so its 3.14*4*4 =50.14 sq.units

Answer 8

Area of circle = (pi) (r^2)

wherein pi = 3.1416
r (radius) = 4

then plug it in the formula...

Area of circle = (3.1416)(4^2)
=(3.1416) (16)
= 50.2656
= 50.27 square units.

hope i had helped you.ü

Answer 9

Pie Are Square

Answer 10

Pi * r^2 = 3.14 * (4)^2 = 50.265
