What is the AREA of this figure?
elena-14-01-66 [18.8K]

Answer:

532m squared is the answer

Step-by-step explanation:

Split the shape into two shapes

one will be a square and the other one a triangle

1) since the length and the width of the square is 18m just Multiply

18x18=324m squared

2) look carefully the width of the square you split is equal to the base of the triangle, so you connect the 18 and the 8 together.

18+8=26m squared

3) Now solve the triangle since you know the height which is 16m squared.

A=lw/2

26x16=416

416 divided by 2 is 208

4) finally just Add

208+324=532m squared

Hopes this helps!

Dominick wants to determine the maximum capacity of a cylindrical bucket that has a radius of 6 inches and a
Karolina [17]

Hey there! I'm happy to help!

To find the volume of a cylinder, you multiply the base by the height.

First, let's find the base.

The base is a circle. To find the area of a circle, you square the radius and multiply by 3.14 (pi).

6²=36

36(3.14)=113.04

We multiply this by the height.

113.04(12)=1356.48

And we round to the nearest tenth.So, the maximum capacity of Dominick's bucket is 1356.5 cubic inches. If you use the entire pi number you would get something more around 1357.2, so that could be the answer if the first is incorrect.

Have a wonderful day! :D
