Answer:
it's the last one *25,000 J
Step-by-step explanation:
Answer:
Step-by-step explanation:
<u>Given AP with:</u>
- a₁= 28, aₙ = 79, Sₙ = 963
<u>Use the formula:</u>
- Sₙ = 1/2n(a₁ + aₙ), sum of the first n terms
<u>Substitute given values and solve for n:</u>
- 963 = 1/2n(28 + 79)
- 963 = 1/2n(107)
- 1/2n = 963/107
- 1/2n = 9
- n = 9*2
- n = 18
Answer:
The answer is 12
Step-by-step explanation:
we multiply it by 2 6 and another 6 is 12 so answer is 12
Question 1: The measure of the radius is the height h of the parallelogram.
Answer: h = r = 9 cm
Question 2: The measure of the distance across the base is the beast approximate base of the parallelogram.
Answer: b = 28.5 cm
Question 3: Calculate 3 times the radius.
Answer: 3 x radius (r) = 3 x 9 = 27 cm
Question 4: What is the mathematical difference between b and 3r? Calculate the absolute value of the two values.
Answer: Ib - 3rI = 28.5 - 3(9) = 28.5 - 27 = 1.5 cm
Question 5: Calculate the area of the parallelogram.
Answer: A = 3r² = 3(9) = 3(81) = 243 cm²
Question 6: Calculate the area of the circle.
Answer: A = πr² = (3.14)(9)² = (3.14)(81) = 254.34 cm²
