9,000 that will be you answer or if is double will be 18,000
Answer:
- area ≈ 176.7 cm²
- circumference ≈ 47.1 cm
Step-by-step explanation:
The radius is half the diameter, so is ...
r = d/2 = 15 cm/2 = 7.5 cm
The area formula is ...
A = πr²
Filling in the radius, we have ...
A = π·(7.5 cm)² = 56.25π cm² ≈ 176.7 cm² . . . area
__
The circumference formula is ...
C = πd
Filling in the diameter, we have ...
C = π·(15 cm) = 15π cm ≈ 47.1 cm . . . circumference
Because there are 4 inside angles the sum of the four angles must equal 360 degrees.
Add the angles to equal 360:
4x + 3x + 2x + 3x = 360
Simplify:
12x = 360
Solve for x by dividing both sides by 12:
x = 360 /12
x = 30
Now you have x, solve for each angle:
ABC = 4x = 4 x 30 = 120 degrees.
BCD = 3x = 3 x 30 = 90 degrees.
CDA = 2x = 2x 30 = 60 degrees.
DAB = 3x = 3 x 30 = 90 degrees.
C. It's important to know that a four sides figure needs the inside angles when added together need to equal 360 degrees.
Answer:
The answer is B.)22
Step-by-step explanation:
3∗5+5∗3
⇒3∗5=2×3−3×5+3×5
=6−15+15
=6
⇒5∗3=2×5−3×3+3×5
=10−9+15
=16
Therefore,3∗5+5∗3
⇒6+16=22
Thus the ans is 22
