Answer:
1: 22cm 2: 30m 3: 78.54
Step-by-step explanation:
1: (6x2)+(5x2)
12+10
22
2: 11+4=15
15x2
30
3: 25/2=12.5
3.14x2=6.28
12.5x6.28=78.54
Answer:
Area of shape = 120 m²
Step-by-step explanation:
Given:
Height of triangle joint = 4 m
Base = 12 m
Width = 8 m
Find:
Area of shape
Computation:
Area of shape = Area of triangle + Area of rectangle
Area of shape = (1/2)(Base x height) + [Base x Width]
Area of shape = (1/2)(12 x 4) + [12 x 8]
Area of shape = 24 + 96
Area of shape = 120 m²
First you can use simple multiplication. Take out the zeroes from 40 and 80. You get 4 and 8. 4 multipled by 8 is 32. so that means that 80 times 40 is 320
Answer: B. 254.34 cm^2
Step-by-step explanation:
The area of a circle is pi times the radius squared.
Using the diameter we have to find the radius.
The diameter is two times the radius meaning that the radius is half the diameter.
18/ 2 = 9
The radius will be 9 cm
Now using the formula v= pi * r^2 , input the value for pie and the radius and solve for v the volume
v = 3.14 * 9^2
v= 3.14 * 81
v = 254.34 cm^2
