Caitlin drew a circle and labeled the circle S. The diameter of Caitlin’s circle is 12 m. Which of the following best represents the area of Caitlin’s circle?
A. 452 m^2
B. 38 m^2
C. 113 m^2
D. 75 m^2
Answer:
C
Step-by-step explanation:
Radius: 12 / 2 = 6 m
Area: 6^2 x pi = 113 m^2
Answer:
c
Step-by-step explanation:
area = π · r²
to change the diameter to radius you just divide by 2
12/2=6 so the radius is 6
then we just plug 6 into r for the circle are formula
6²=36
36x3.14=113.04 so her best answer choice is c

what grade are u in that's easy lolll
Step-by-step explanation:
y=-2(x + 1)2+3
write in standard form
y = -2(x + 1)² + 3
y = -2(x² + 2x + 1) + 3
y = -2x² - 4x - 2 + 3
y = -2x² - 4x + 1
Answer:
4x + y = -1
just simplify then re-write

C
A. ZA and C
B. ZA and ZB
C. BC and AC
D. AB and
The side AC of the triangle is included between angles A and C.
What is an Included Side?An included side is a side that is in between two angles in a triangle, where the rays of the angles overlap.
Given is a triangle, we need to determine the angles which includes the side AC,
Since angle A and angle C forms side AC, AC is included between: A. ∠A and ∠C.
Thus, in triangle ABC, side AC lies in between angle A and angle C.
Therefore, since angle A and angle C forms side AC, AC is included between ∠A and ∠C.
Hence, the side AC of the triangle is included between angles A and C.

Answer:
305.5 sq inches
Step-by-step explanation:
A (trapezoid) = 1/2·h·(sum of bases)
A = 1/2(17)(8 + 23)
A = 8.5(31)
A = 263.5
A(triangle) = 1/2·b·h
A = 1/2·(6)·(17-3)
A = 3(14)
A = 42
Total Area = 263.5 + 42.0 = 305.5 sq in

Answer:
A = 40 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂)
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 5, b₁ = 10 and b₂ = 6 , then
A = [tex]\frac{1}{2}[/tex] × 5 × (10 + 6) = 0.5 × 5 × 16 = 40 cm²
please help i’ve done a (5x) but i need b) and c)
Answer:
b would be 6xy
c would be 6xy as well
Step-by-step explanation:
Not really sure how to explain it, I just know it
Answer:
b) 6xy
c) 6xy
Step-by-step explanation:
b) 6 × x × y
Since there are no like terms, just straight away remove the multiplication signs. So the answer is:
= 6xy
c) 2 × x × 3 × y
2 and 3 are like terms since they are both natural numbers (positive integers), you can multiply 2 with 3. The answer will be:
= 6xy

how can I solve -7(-8+10-5) please explain
Answer:
so is actually bidmas of bodmas however you want to call it but what's in the brackets you always have to do first so what you would do is because as for subtraction comes last you 1st to -8+10 which is to then you do 2-5 which is -3 so then you do -7 times -3 which because if two minuses or times or multiplied like everyone say it would be a positive so that

What do I do I don’t know the answer
Answer:
B) 114.511m^3
Step-by-step explanation:
Formula of a cylinder is πr^2 x h
r = radius (half of diameter)
h = height
Since it is 3/4 full you only do 3/4 of the height so- 0.75 x 9.60 which equals 7.2
Half of the diameter is 2.25. 2.25^2 = 5.0625.
The volume of the cylinder = 5.0625π x 7.2
By solving this, you will get approximately 114.511 m^3 as your answer.

Solve each equation for y. Use the given values for x to find the values for y. Write answers as ordered pairs.
Answer:
1. x =-4 (-4,27)
x =0 (0,3)
x = 2 (2 , -9)
2. x = -1 (-1 , 3)
x = -2 (-2 , 2)
x = -3 ( -3, 1)
3. x = -3 (-3 , 13)
x = 1 (1 , 1)
x = -2 ( -2, 10)
4. x =2 (2 , 24)
x = 3 (3 , 30)
x = -2 (-2 , 0)
5.x = -3 (-3 , -2)
x = 2 (2 ,-12 )
x =4 (4 , -16)
6. x = -1 (-1 , -2)
x = 0 (0 , 2)
