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

CAN SOMEONE PLEASE EXPLAIN WHY THE ANSWER FOR THIS IS 4N+15. THIS IS 10 MINUTES PAST DUE!!! TAKE 20 POINTS​
Oduvanchick [21]
The first part of the expression 4n is because n is the amount of almond trees and to find the walnut trees, you need to multiply the number of almond trees (n) by for (4n). you would also add 15 because it says he has 15 more than 4 times as many walnut trees.

so here's the breakdown of the sentence:

Daquan has 15 more than (15 +) 4 times as many (4n) walnut trees in his orchard as he has almond trees.

hopefully this makes sense! have a nice day

What is the radius of a cylinder with a volume of 3,165.12 cubic centimeters and a height of 7 centimeters?
leonid [27]

Answer:

Radius = 12 cm

Step-by-step explanation:

Given:

Volume of the cylinder is, V=3165.12 cm³

Height of the cylinder, h= 7 cm

Let the radius be r

Using the formula for volume of cylinder,

V=\pi r^2h

Plug in 3165.12 for V, 7 for h and solve for r.

3165.12=\pi r^2(7)\\3165.12=\frac{22}{7}\times 7\times r^2\\3165.12=22r^2\\r^2=\frac{3165.12}{22}\\r^2=143.869\\r=\sqrt{143.869}=11.99\approx=12\textrm{ cm}

Therefore, the radius of the cylinder is nearly 12 cm.
