<em> The radius of a circle is 10 m. Find its area to the nearest whole number.</em>
<em />
<em />
We're asked to find the area of the circle, which we can find using the following formula:-
Where:-
- π = pi [3.14...]
- r=radius (10 m)
<h3>What we need to do to find the area:-</h3>
Substitute 10 for r and 3.14 for π:-
On simplification,
On further simplification,
The Area is:-
Note:- Area is always measured in units² (units squared)
<h3>Good luck with your studies.</h3>
Need more info,
But as 2 is the gradient, and 1 is the y-intercept. If you’re trying to find the value of y and x, sub 0 into x: y= 2(0) + 1
So y would equal 1
Then sub 0 into y: 0= 2x + 1
So x would equal -1/2

8 and then i am not sure the rest
Step-by-step explanation:
Answer:
∠1 and ∠3
Step-by-step explanation:
Angles 1 and 3 are adjacent to angle 4 because they are directly next to it
Solve for x in x+ 3y + 2z = 8
x = 8 - 3y - 2z
Substitute x = 8 - 3y - 2z into 3x + y +3z = -10
24 - 8y - 3z = -10
Substitute x = 8 - 3y - 2z into -2x - 2y - z = 10
-16 + 4y + 3z = 10
Solve for y in 24 - 8y - 3z = -10
y = -3z - 34/8
Substitute y = -3z - 34/8 into x = 8 - 3y - 2z
x = 8 + 3(3z - 34)/8 - 2z
Substitute y = -3z - 34/8 into -16 + 4y + 3z = 10
-16 + -3z + 34/2 + 3z = 10
Solve for z in -16 + -3z + 34/2 = 3z = 10
z = 6
Substitute z = 6 into x = 8 + 3(3z - 34)/8 - 2z
x = -10
Substitute z = 6 into y = -3z - 34/8
y = 2
<u>Therefore,</u>
<u>x = -10</u>
<u>y = 2</u>
<u>z = 6</u>
<u>D. -10, 2, 6</u>
