Find the surface area of the cone. Leave your answer in terms of A 70 cm^2 . B. 98 cm^2 C. 119 cm^2 D. 129 cm^2
olganol [36]

Answer: OPTION C (119π cm²)

Step-by-step explanation:

Yon can use the following formula for calculate the surface area of a cone:

SA=rl\pi+r^2\pi

Where r is the radius and l is the slant height.

Based on the figure shown attached, you have that:

r=7cm\\l=10cm

Therefore, when you susbtitute these values into the formula shown above, you obtain that the surface area of the cone is:

SA=(7cm)(10cm)\pi+(7cm)^2\pi=119\picm²

AURORKA [14]

Answer:

Option A. 2x^{3}+7x^{2}+12x-8

Step-by-step explanation:

we have

(x^{2}+4x+8)(2x-1)

Applying the distributive property

(x^{2}+4x+8)(2x-1) =x^{2}(2x)-x^{2} +4x(2x)-4x+8(2x)-8\\ \\=2x^{3}-x^{2} +8x^{2}-4x+16x-8\\ \\= 2x^{3}+7x^{2}+12x-8

s2008m [1.1K]

Answer:

First,

the age of the son: s

the age of the father is 2 less than 7 times the age of his son: 7s - 2

In 3 years, the sum of their ages will be 52, In 3 years, the age of the sun will

increase 3, so s+3. Also, the age of his

father also increase 3, (7s-2)+3

(s+3)+ [(7s-2)+3] = 52 is the equation.

zhuklara [117]
<h3>Answer:  43 km per hour</h3>

==================================================

Work Shown:

total distance = 43+40+46 = 129 km

total time = 1+1+1 = 3 hours

average speed = (total distance)/(total time)

average speed = (129 km)/(3 hrs)

average speed = (129/3) (km/hr)

average speed = 43 km per hour
