Mathematics

LenaWriter [7]3 years ago

When finding an area of a circle, you need to know radius. The formula of the area of a circle is A=(pi symbol)(r squared). In this case the radius is 4.5mm because you need to divide the total by 2. Multiply 4.5mm and 4.5mm, which is the r squared. Finally multiply your answer to pi and that is the area of the circle.

Lance and Alex have 70 pencils. Lance has 4 times as many pencils as Alex. Alex's pencils are shared equally among 2 children. H
gogolik [260]


let l = lance, and a = alex.

so: l + a = 70

and l = 4a

Putting the value for l in the first equation:

4a +a = 70

5a = 70

a = 14.

So Alex has 14 pencils. And Lance has (70-14) 56 pencils.

And if each child gets half of Alex' pencils, then each child will have 7 pencils.
