The arch of a bridge has dimensions as shown, where thmeasure 2m as its highest point and its width is 6m. What is theradious of the circle that contain the arch.e arch2mm-_- B

Answer»

The height of the arch of the bridge = h = 2m

The width of the arch of the bridge = w = 6m

In order to find the radius of circle which contain this arch we use the following formula:

r = h/2+w^2/8h

substituting values of h and w in the above formula

r = 2/2+6^2/8x*2

simplifying

r = 1 + 36/16

r = 1 + 2.25

r = 3.25m

So, radius of circle which contain this arch is 3.25m.

11. If 21=53', 22 = 65° and 23 = 43°, find the measures of Zx and Zy. Justifyyour answer.32

Answer»

angle Y is 47 and X is 59

y+3+90° =180° 3 = 43° so y = 180°-90°-43°= 47°x = 180°-53°+68°=59

angle Y=41 and angle X=59

Given,angle 1=53°,, ,,. 2=65°,,. ,,. 3=43°A/C,triangle's interior angles property,y=180° - (90°+43°)y=47°A/C,exterior angles property of a triangle-angle[x+1]=angle[y+2] x+53°=47°+65° x =112°-53° x =59°so, x=59°, y=47°.

y+390°=180°3=43°soy=180°-90°-43°=47°x=180°-(53°+68°)=59°

43+ y +90 =180 y=180-133=47and 53+x+180-112=180x=59then x=59 y=47

angle x=62angley=47

x= 59y= 68

3. A gulab jamun, contains sugar syrup up to about30% of its volume. Find approximately how muchsyrup would be found in 45 gulab jamuns, eachshaped like a cylinder with two hemispherical endswith length 5 cm and diameter 2.8 cm (see Fig. 13.15).

Answer»

Step-by-step explanation:

Radius of hemisphere =1.4cm

Volume of hemisphere =2×22/7×1.4×1.4×1.4

=5.75cm3

Volume of 2 hemisphere

=2×5.75

=11.50cm3

Height of cylinder =5_2 (1.4)

=5-2.8

=2.2cm

Volume of cylinder =22/7×1.4×1.4×2.2

=13.55cm3

Total volume of gulab jamun

=11.50+13.55

=25.05cm3

Volume of sugar syrup in 1 gulab jamun

=30/100×25.05

=7.51cm3

Volume of sugar syrup in 45 gulab jamun

=45×7.51
