Use the formula for the length of an arc:-
L = r C where r = radius and C = angle subtended in radians So here we have:_
18 = r * 130 * pi / 180
18 = 2.269 r
r = 7.93 cm to neraest hundredth
Add the exponents since it’s multiplication, so it would be 2a^7, hope this helps
Area of the triangle = (1/2)*base* height = (1/2)*3*6 = 9 sm²
We have 4 triangles like this one ,
so area of 4 triangles = 9*4 = 36 cm².
Area of the square = 3*3 = 9 cm²
Surface area here means area all triangles + area of the square =36 +9 =
= 45 cm ²
Answer is 45 cm².
Answer:
875
Step-by-step explanation:
The answer is no, he's not correct.
You're looking at 9/1000, which means you move the (invisible) decimal point after 9 three places to the left (because you're dividing and there are 3 zeros after the 1 in 1000). This would give you 0.009.
