Can someone help me to find tsa of entire solid ?

o-na [289]

Step-by-step explanation:

Radius is same in both cones....

Slant height of lower cone = 50 cm ( by applying Pythagorean theorem )

TSA of the lower cone = 22/7 × 14 × ( 14 + 50 )

= 2816 cm^2

Total height of the solid = 52.8 cm

Height of the upper cone = 52.8 - 48 = 4.8 cm

TSA of the upper cone = 22/7 × 14 × ( 14 + 4.8 )

= 827..2 cm^2

TSA of the solid = 2816 + 827.2 = 3643.2 cm^2

Find value of x, show your work

Zina [86]

Here is your answer

$\huge x=\frac{35}{2}cm= 17.5cm$

REASON :
AB//CD

So,

/_A=/_D ... (alternate int. angles)

/_B=/_C ... (alt. int. angles)

So,

Tri.ABE~Tri.DCE... (by AA similarity)

Therefore,

Corresponding sides are proportional

i.e.

$\frac{AE}{DE}=\frac{AB}{DC}$

$\frac{5}{x}=\frac{4}{14}$

$x=\frac{5×14}{4}$

$x=\frac{5×7}{2}$

$x=\frac{35}{2}$

Solve for x 0.3x=0.01x+2.9

PolarNik [594]

Answer:

0.3x= 0.01x+2.9 -->

--> -0.01x -0.01x -->

--> 0.29x= 2.9 -->

--> /0.29 /0.29 -->

--> x=10

Step-by-step explanation:

1: subtract 0.01x from both sides

2: divide your answer (0.29) on both sides

3. you answer is now whatever x is (10)
