The surface area of the solid is about ____ inches squared

Dafna11 [192]

Answer:

Surface area of the whole figure $= 320.28inch^2$

Step-by-step explanation:

The surface area of the figure :

Surface area of the cylinder(excluding top)+Surface area of the cone(excluding bottom)

Radius of the cylinder=3 inch and Height of cylinder=13 inch

Surface area of the cylinder with one circular face

$=2\pi rh+\pi r^2$

As, $\pi =\frac{22}{7}= 3.14$

$=(2*3.14*3*13)+(3.14*3*3)\\\\=244.92+28.26\\\\=273.18inch^2$

Surface area of the cone excluding base:

$=\pi *r*l$

l= slant height=5 inch r= radius= 3 inch

Surface area of the cone = $3.14*3*5$

$=47.1inch^2$

Total surface area of the whole figure $=273.18+47.1$

$= 320.28inch^2$

1. A parachutist is 800 feet above the ground when she opens her parachute. She then falls at a constant rate of 5 feet per seco

Alexandra [31]

Answer:

h = -5*t +800

Step-by-step explanation:

The initial value is 800 ft

She is falling at a rate of 5 ft per second

That would be -5ft/s

We can write this in the form

y = mx+b

h = -5*t +800 where t is the number of seconds and h is the height above ground

The first two terms of an arithmetic sequences are 7 and 3.

Katyanochek1 [597]

Answer:

1.1.1) -61

1.1.2) Term 42

Step-by-step explanation:

Tn= dn (difference) + t0 (term 0)

Tn= -4n+ 11

You can now take this general rule to find out the other terms.

Tn= -4(18)+11

Tn= -61

And the term -157

Tn= -4n+11

-157= -4n + 11

-157 - 11= - 4n

-168= -4n

-168/-4= n

42= n
