Answer:
Circumference is 28.26 ft
Area is 14.13 ft^2
Step-by-step explanation:
9×3.14=28.26
9/2=4.5
4.5×3.14=14.13
Answer:
n = 24
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= =
hence
= ( cross- multiply )
35n = 30 × 28 = 840 ( divide both sides by 35 )
n = = 24
Answer:
Directly related
Step-by-step explanation:
Step one:
Given data:
House
Brick
By convention Bricks are used to build houses and the more bricks used the bigger the house built
Step two
Mathematically
The relationship between houses and Bricks is a direct proportional relationship
Answer:
area= 604 cm^2
perimeter=376 cm
Step-by-step explanation:
radius(r)=28/2
=14 cm
<em>area of the semicircle</em>=2r*theta /360
=2*22/7*14*180/360
=44cm^2
<em>area of the rectangle</em>=l*b
=28*20
=560 cm^2
<em>total area</em>=semicircle area+rectangle area
=560+44
=<u>604 cm^2</u>
<em>arc length</em>=*theta/360
=22/7*14*14*180/360
=308cm^2
<em>perimeter</em>=28+20+308+20
=<u>376 cm</u>

Area = base x height /2
Base =26.5
Height =40
26.5 x 40 /2 = 530
