In plain and short, we simply divide the "whole" by the sum of the ratios, and distribute accordingly.
now, 100% is the whole of any amount, so we'll divide 100% by (3+1).
Answer:
32cm and 28cm
Step-by-step explanation:
Area of a trapezium=0.5 ( sum of parallel sides ) × height
600=0.5( 4+a+a)×20
where a is the length of the shorter side
600÷0.5=(4+2a)×20
1200=(4+2a)×20
1200÷20=4+2a
60=4+2a
60-4=2a
56=2a
56÷2=a
28=a.
since the longer side is 4 cm more than th shorter side , 28 +4=32
Answer:
4.30 inches
Step-by-step explanation:
Given data
Volume of basket ball= 334cubic inches
We know that the expression for the volume of a sphere is given as
Volume of sphere= 4/3πr^3
334= 4/3πr^3
334=4/3*3.142*r^3
334=4.189*r^3
r^3= 334/4.189
r^3=79.73
cubic root both sides
r= ∛79.73
r=4.30 inches
Answer:

You multiply the base of the triangle and the width. Then divide it by 2
Answer:
option (A) "r".
Step-by-step explanation:
Length of the shape formed by the sectors is which is half of the perimeter of the given circle, with the radius r.
Circle is divided in eight sectors and arranged horizontally as shown in the figure.
Therefore, height of each sector will be equal to the radius "r" of the circle.
Answer is option (A) "r".
