The cone and cylinder below have equal surface area
marissa [1.9K]

Answer:

Option B, False

Step-by-step explanation:

<u>Step 1:  Get the surface area formulas for both shapes</u>

Surface Area Formula for Cone:  A = \pi * r(r + \sqrt{h^{2} + r^{2}})

Surface Area Formula for Cylinder:  A = 2\pi rh+2\pi r^{2}

<u>Step 2:  Plug in the values and solve</u>

Cone:  A = \pi * r(r + \sqrt{(3r)^{2} + r^{2}})

Cone:  A = \pi r^{2} + \pi \sqrt{10}r^{2}

Cylinder:  A = 2\pi r*r+2\pi r^{2}

Cylinder:  A=4 \pi r^{2}

<u>Step 3:  Compare</u>

<u />\pi r^{2} + \pi \sqrt{10}r^{2}\neq 4 \pi r^{2}

They are not equal, therefore the answer is False.

Answer:  Option B, False

What is the sign of the product (–5)(–3)(–8)(–6)? Positive, because the products (–5)(–3) and (–8)(–6) are negative, and the pro
chubhunter [2.5K]

Answer:

The product (–5)(–3)(–8)(–6) should be Positive.

Step-by-step explanation:

The product of 2 negative numbers equal a positive product.

N * N = P

-5*-3=15

-8*-6=48

The product of 2 positive numbers is positive.

P * P = P

15 * 48 = 720

Your answer should be: Positive because the products (–5)(–3) and (–8)(–6) are positive, and the product of two positive numbers is positive.

73 feet per second

Steps-
Miles to cover- 50 miles = 50*5280 feet = 264,000 feet
Time it takes- 1 hour = 1*60*60 seconds = 3,600 seconds

So speed is- 264,000 feet per 3,600 seconds = 264,000 / 3,600 = 73.33 ft per second
