Find the perimeter of this semi-circle with diameter, d = 45cm. Give your answer rounded to 1 DP.

Answers

Answer 1

Answer:

P = 70.6 cm

Step-by-step explanation:

Given that,

The diameter of the semicircle, d = 45 cm

Radius, r = 22.5 cm

We need to find the perimeter of the semicircle. The formula for the perimeter of a semicircle is given by :

[tex]P=\pi r\\\\P=\pi \times 22.5\\\\P=70.6\ cm[/tex]

So, the required perimeter is 70.6 cm.

Answers

Answer:

x=35 y=72.5

Step-by-step explanation:

x is equal to 35 because they are vertical angles. y is equal to 72.5 because if you use the equation y + y + 35 = 180 and subtract 35 then divide 145 by 2, you would get 72.5

QRS~TUV. what is the measure of V?

Answers

Answer:

70°

Step-by-step explanation:

As we can see that that triangles are similar so

angles are equal

< U = 47° and < T = 63°

So now

< U +< T + <V = 180°< being sum of angles of triangle >

47° + 63° + < V = 180°

< V = 180° - 110°

< V = 70°

Hope it will help :)❤

Answer:

70 degrees

Step-by-step explanation:

Similar triangles are different in size, but same in angles. That means...

Angle R is congruent to Angle U, Angle Q is congruent to Angle T.

By the Triangle Sum Theorem, all triangles add to 180 degrees.

Angle U + Angle T + Angle V = 180 degrees

47 + 63 + Angle V = 180

Angle V = 70

A circular plate has a circumference of 119.32cm. Calculate the diameter.

Answers

Answer:

Diameter is equal to 38 cm.

Step-by-step explanation:

We know that the circumference equals  πd (where d is the diameter).

If we round the value of π to 3.14 then we will get...

πd = 119.32

(3.14)d = 119.32

d = 119.32 / 3.14

d = 38 cm

Therefore the diameter is equal to 38 cm
