Answer:
284.52
Step-by-step explanation:
total area = area of semi circle + area of rectangle
area of semicircle = pi r^2 /2.
= 3.14 * (12/2) ^2 ...divided by 2
= 56.52
area of rectangle = length * breadth
= 19*12
= 228
I don’t know how to do it,, but use photomath, it’s perfect for these type of questions
Answer:
1 week
Step-by-step explanation:
Given:
p = 12w
Where,
w = number of weeks the office has been on the new recycling plan
p = total kilograms of paper recycled.
How many weeks will it take Scott's office to recycle a total of 12 kilograms of paper?
Find w when p = 12
p = 12w
12 = 12w
Divide both sides by 12
w = 12/12
= 1
w = 1 week
Answer:
(-A)^2 for A = 5
(-5)^2
