31.4/3.14=10
10/2=5
5*5*3.14= 78.5 cm square
The whole area is a rectangle one. In order to get the area of a rectangle, the formula is length multiplied by the width. The length of the area is 7.5 meters and the width is 5.3 meters. Covering the whole area with foam needs 39.75 square meters of it.
Answer:
less
Step-by-step explanation:
because 1.3= 1 3/10 and 1 3/5 is equal to 1 6/10 there for it less than
Answer: 91 guests
Step-by-step explanation:
Given the available furniture legs to be 364, where each seat has 4 legs
We will divide 364 by 4 to get the number of available seats.
364/4 = 91 seats
If 91 seats are available and it is set at 1 seat per guest,
Number of guests will be 91 seats/1 = 91, therefore, 91 guests will be available.
To get the congruent angles we shall use the sine rule since we have the length of at least 1 side and the values of the angles.
Base length=12 inches
Base angles=50°
Third angle=180-(100)=80°
thus applying the sine rule we shall have:
a/sin A=b/sin B=c/sin C
thus we can get the congruent side as follows:
a/sin 50= 12/sin 80
a=(12 sin 50)/sin 80
a=9.334 inches
since the sides are congruent then the other congruent side will have a length of 9.334 inches
