The fourth one also

surface areaof ahemispherethen 2 π r2

total surface area =3πr²

volume = 2/3πr³

put the value of r in the formulae and find the solution

Volume of box/volume of the cube100*100*100/10*10*101000000/10001000cubes

As we know that, 1'=60''=>1''=(1/60)'.

and 15''=(15×1/60)'=(1/4)'

again, we know that 1°=60'=>1'=(1/60°)

so (1/4)'=(1/240)°. =(1/240×π/180)c.

let the angle between the man and the ground be x°.

Then tan(π/43200)=167.64/h

=>.000072=167.64/h

=>h=2328333cm.

(approx).where h is the distance from the man to the angle.

r=1.2 unitsh=7 units∴Total Surface Area=2πrh+2πr²={(2×3.14×1.2×7)+(2×3.14×1.2×1.2)}=61.795 square units

Thank you SO much friend

2x+2 = 5x -10; 5x-2x = 12; 3x=12; x=12/3=4; y/3=6;; y=6×3=18;

x=4y=18is correct answer

In a Euclidean space, the sum of measures of these three angles of any triangle is invariably equal to the straight angle, also expressed as180 °, π radians, two right angles, or a half-turn.

thnx

perimeter=10+4+3+2+4+2+3+4=32 ftArea=(10*4)+(4*2)=40+8=48ft

perimeter=2(l+b)2(10+4)+2(4+2)=28+12=40 ftarea=l×b(10×4)+(4×2)=40+8= 48 square ft

PERIMETRE OF FIGURE = SUM OF ALL SIDES= 4FT + 1FT + 3FT + 5FT = 13FT

please like my answer if you find it useful

thankyou for your answer a lot I appreciate it but I just dont understand the second line but I would still like your answer. thankyou again😊

sry that you didn't understand the second line.area of shaded region will be total area( area of rectangle)- area of two circle area of rectangle= length ×breadtharea of circle=π(radius)^2length of rectangle= 39 ft(given)breadth of rectangle=27ft(given)radius of circle=9ft(giventhen substitute all the value..you will get answer

thankyou so much I understand now!

Ans :- To prove that thediagonalsof aparallelogram bisect each other, we will use congruent triangles: (alternate interioranglesare equal in measure) Also, side AB is equal in length to side DC, since opposite sides of aparallelogramare equal in length.

Volume of hemisphere = S.A of hemisphere2/3πr^3=3πr^22/3r=3r=9/2diameter =9/2x2=9 Ans

Volume of hemisphere = S.A of hemisphere

2/3πr^3=3πr^2

2/3r=3

r=9/2

diameter =9/2x2

=9
