Answer:
Step-by-step explanation:
The formula of a lateral area of a cone:
r - radius
l - slant height
The formula of a surface area of a cone:
We have r= 8in and l = 21in. Substitute:
Answer: m = d/4 - n/4
Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.
Please mark me as brainliest
SA= 49.5 (m but it says no units)
Explanation: find the area of one of the triangles, A=(b*h)/2, and then one of the rectangles, A=l*w. Multiply the triangles area by two, there are two triangles. Multiply the rectangles areas by three, there are three rectangles. I’ve included calculations in the picture below.
Answer:
If its per month then its 900
Step-by-step explanation:
3600/4 = 900
900*4 = 3600
Answer:
A =78.5
Step-by-step explanation:
We need the radius to find the area of a circle
r = d/2 = 10/2 =5
The area of a circle is given by
A = pi r^2
A = 3.14 (5)^2
A =3.14 (25)
A =78.5
