Help with my year 10 Maths -.-

[!!!Liam!!!]

I rushed it because I wanted to go... anyway I need to find the area of them! Please tell me what to do

[Detox]

To find the semi circle in the square:

Area of circle = pi x r squared so 10 x pi squared and divided by 2. And divide it by 2 again because it is half a circle.


Area of the square:

Take away the area of the semi circle from 100 (Area of square = Length x Width = 10 x 10)


Ice Cream Shaped thing:
1) Semi circle: Pi x 8 sqaured and half it coz its half a circle again. Or Pi x 4 squared.
2) Triangle: Base x Height / 2. So 8 x 6 = 48 /2 = 24

Will try and do the rest in a minute.

I take it I will need a calculator :p brb

Yeah you need it for working out things with pi in.

I dont have the radious for the semi circle thingy majig

[!!!Liam!!!]

Uhmmm I will ring Jess later Ty

The radius is half the diameter. The diameter is the width of the circle. You have the lengths you need to work it out. Good luck
