Answer:
<h3>Area =Pi r2</h3>
=3.14×10x10
=3.14×100cm2
=3.14cm2
<h3>Perimeter = 2 pi r</h3>
=2 ×3.14×10
=6.28cm
Or =Pi d
= 3.14 ×20cm
=62.8cm
<h3>Note:</h3>
R means radius
D means diameter
radius is half of a diameter e.g radius is10 and diameter is 20
I can recommend you watching yt videos it helped me alot

Solution is x=2 and y=-3
check the slopes since both are in slope int form
y=mx+b
m=slope
b=yint
we see one line has a slope of -2 and yint of 1
another one has a slope of 1/2 and yint of -4
y=-2x+1 and y=1/2x-4
1/2x-4=-2x+1
last one
Answer:
angles on a straight line add up to 180°
Step-by-step explanation:
90+51=141
180-141
=31
<MLJ=31°
72+90=162
180-162=18
<KJL=18°
Answer:
1.875.
Step-by-step explanation:
Step 1: Multiply the whole number by the denominator: 1 × 8 = 8.
Step 2: Add the product you got in Step 1 to the numerator: 8 + 7 = 15.
Step 3: Divide the sum from Step 2 by the denominator: 15 ÷ 8 = 1.875.
