Here, we are required to find the area of the paper board given after the semicircle is cut out of it
Area of the paper board thatremains is 423 in²
Length = 29 in
Width = 20 in
Area of a rectangle = length × width
= 29 in × 20 in
= 580 in²
Area of a semi circle = πr²/2
π = 3.14
r = diameter / 2 = 20 in / 2 = 10 in
Area of a semi circle = πr²/2
= 3.14 × (10 in)² / 2
= 3.14 × 100 in² / 2
= 314 in²/2
= 157 in²
The semicircle is cut out of the rectangle
Find the area of the paper board that remains after the semicircle is cut out of it by subtracting the area of a semi circle from the area of a rectangle
Area of the paper board that remains = Area of a rectangle - Area of a semi circle
= 580 in² - 157 in²
= 423 in²

Answer:
480 people
Step-by-step explanation:
Set up an equation where x is the number of people surveyed:
180 = (x)(0.375)
Solve for x:
180 = (x)(0.375)
480 = x
So, Annette surveyed 480 people
Answer:
Area=80 units squared
A=base*height
A=base*height/2
Step-by-step explanation:
7*8=56/2=28
7*8=56/2=28
3*8=24
28+28+24
56+24
80
(2^8 . 5^-5 . 19^0)^-2
using PEMDAS
this = (2^8 * 1/5^5 * 1)^-2
= (5^5 / 2^8)^2
= 5^10 / 2^16
The answer is 8m im serious
