Answer:
Total area is 198.6cm²
Step-by-step explanation:
This problem bothers on the mensuration of flat shapes.
Step one
From the given figure the two semi circles left and right can be resolved as a whole (a complete circle) with diameter d 10cm
Radius r = 10/2= 5cm
Area of circle A= πr²
A= 3.142*5²
A= 3.142*25
A= 78.55
A= 78.6cm²
Step two
The remaining part of the shape is a rectangle with length (22-10)= 12cm
I.e the 10 is as a result of the radius of the two semi circles = r+r= 5+5=10
The rectangle has a width of 10cm
Area of rectangle A=12*10= 120cm²
Hence the total surface area of the shape
Total area = 120+78.6
Total area = 198.6cm²
Answer:
4. 118 kg
w = 450 j , d = 3.8 m
w = mgh ⇒mg = w / h ⇒m = 450/3.8 = 118 kg
5. 9806.65 Joules
6. 25 J
Answer:
I don't agree, because the triangle is dilated, so it's angle measures won't change; only the side lengths will. Two shapes are congruent if they are identical in shape and size. The side lengths of both triangles are not equal in size to each other.
Step-by-step explanation:
Answer:
10(q-3)
last option
please brainliest me btw
Step-by-step explanation:
The expression states 10q-30
The GCF is 10 (30 GCF by 10 Is 10)
Factor out 10
After, divide all the terms by 10
10 (10q/10) - 30/10
Simplify this and we get
10(q-3)
so in conclusion, it is the last option.
