A. If you know the diameter, you can find the radius of a sphere by dividing the diameter in half. If you know the circumference, you can find the radius by dividing the circumference by 2 times pi
B. π × r2 × h
Answer:
A₍ₙ₎ = - 74 + (n-1) x 6
Step-by-step explanation:
A₍ₙ₎ = A₍₁₎ + (n-1) x d
A₍₁₈₎ = 28 = A₍₁₎ + 17 x d ..... (1)
A₍₄₀₎ = 160 = A₍₁₎ + 39 x d .....(2)
(2)-(1) 132 = 22d
d = 6
A₍₁₎ = 28 - 17 x 6 = -74
formula: A₍ₙ₎ = - 74 + (n-1) x 6
Answer:
we have to find the quotient and the remainder when (x³ + 5x + 3x² + 5x³ + 3) is divided by (x² + 4x + 2) ♥9 dividend = x² + 4x + 2 using Euclid division lemma, x² + 4x + 2) x² + 5x³ + 3x² + 5x + 3(x³ - 4x² + 19x - 65 x² + 4x² + 2x³ - 4x² + 3x² + 3x² - 4x*-16x³8x² 19x³ + 11x² + 5x 19x³ +76x² + 38x -65x²-33x + 3 -65x²-260x - 130 +227x + 133 Therefore the quotient is x² - 4x + 19x - 65 and remainder is 227x + 133
Circumference = πD

Given that the circumference is 75cm, find Diameter:
------------------------------------------------------------------------
πD = 75
D = 75 ÷ 3.14
D = 23,89 cm
------------------------------------
Find Radius:
------------------------------------
Radius = Diameter ÷ 2
Radius = 23.89 ÷ 2
Radius = 11.94 cm
------------------------------------
Find Surface Area:
------------------------------------
Area = πr²
Area = 3.14 x 11.94²
Area = 447.65 cm²
------------------------------------
Answer: 447.65cm²
------------------------------------
