Answer:
OOO I KNO ITS 7.2 15.6 OK
Step-by-step explanation:
SO WHAT YOU DO IS 7.2 THEN ROUND SO THEN ITS 6 THEN 15.6 16
THEN YOU WILL DIVIDE. I HOPE THIS HELPS
THIS IS HOW I LEARNED BUT I COULD BE WRONG.
PLZZZ BRAINLYIST!!!!
OH AND HAVE A WONDER FULL DAY
The area of the shaded region is
.
Solution:
Given radius = 4 cm
Diameter = 2 × 4 = 8 cm
Let us first find the area of the semi-circle.
Area of the semi-circle = 


Area of the semi-circle =
cm²
Angle in a semi-circle is always 90º.
∠C = 90°
So, ABC is a right angled triangle.
Using Pythagoras theorem, we can find base of the triangle.




cm
Base of the triangle ABC =
cm
Height of the triangle = 4 cm
Area of the triangle ABC = 

Area of the triangle ABC =
cm²
Area of the shaded region
= Area of the semi-circle – Area of the triangle ABC
= 
= 
Hence the area of the shaded region is
.
Answer:
The answer is (x+y)^3
Step-by-step explanation:
using the division/subtraction law of indices
In indices division is equal to subtraction on powers
(x+y)^5 ÷ (x+y)^2
=(x+y)^5-2
=(x+y)^3
Replace 1/8 into the equation for p and you get 2 - 10 which is -8
