Total surface area = lateral area of cone + lateral area of cylinder + area of base of cylinder:
cone: πrL = π(5cm)(13cm) = 65πcm²
cylinder: 2πrh = 2π(5cm)(12cm) = 120πcm²
base: πr² = π(5cm)² = 25πcm²
total surface area = 65πcm² + 120πcm² + 25πcm² = 210πcm²
((3x^2)^a - (4y^a)(z^3a))^2
First, expand.
((3x^2)^a - (4y^a)(z^3a)) ((3x^2)^a - (4y^a)(z^3a))
Combine
3^(2a) - x^(4a) - 8 * 3^(2a)x^(2a)y^(a)z^(3a) + 16y^(3a)z^(6a)
hope this helps
Answer:
Step-by-step explanation:
A. k/5 = 3: Isolate k by multiplying both sides of this equation by 5:
k = 15
B. 3.5d = 70; Divide both sides by 3.5, obtaining d = 20
C. 4 1/2 = 1 1/2n; Rewrite 4 1/2 and 1 1/2 as improper fractions:
9/2 = (3/2)n. Now multiply both sides by (2/3): 3 = n
Answer:
D. 40
Step-by-step explanation:
Area of triangle: A = 1/2bh
We have <em>b </em>and <em>h</em> already, so simply plug it in:
A = 1/2(16)(5)
A = 8(5)
A = 40 units²
