Step-by-step explanation:
Answer:
(a)f(4) square cm.
(b)f(10.91)-f(10.9) Square centimeter.
Step-by-step explanation:
f(r)=the area of a circle (in square cm) that has a radius of r cm.
(a)Area (in square cm) of a circle whose radius is 4 cm.
Since r=4cm
Area of the circle = f(4) square cm.
(b) When the radius of the increases from 10.9 to 10.91 cm.
- Area of the circle with a radius of 10.91 = f(10.91) square cm.
- Area of the circle with a radius of 10.9 = f(10.9) square cm.
Change in the Area = f(10.91)-f(10.9) Square centimeter.
From second equation y = 8 - x so
7x + 2(8 - x) = -14
5x = -14 - 16 = -30
x = -6
and y = 8 - -6 = 14
Answer x=-6,y=14
Answer: This data is quantitative data because the measurement of voltage deals with numerical values.
Answer:
Option C:- 1,232cm³
Step-by-step explanation:
radius r = 7 m
height h = 24 m
slant height s = 25 m
volume V = 1231.50432 m3
lateral surface area L = 549.778714 m2
base surface area B = 153.93804 m2
total surface area A = 703.716754 m2
