Answer:
13.6
Step-by-step explanation:
Answer:
-4
Step-by-step explanation:
-3-1= -4
A negative minus a positive= a "larger" positive.
A = pi r^2 / 2
if 22mm = radius
then
A = (3.14 * 22^2) / 2
A = 759.88
if 22mm is the diameter
then
A = (3.14 * 11^2) /2
A = 189.97
Answer:
A
Step-by-step explanation:
You first divide 4.2 and 0.7, which is 6. hen you subtract/add left to right, and that equals 6.2, and A is 6.2.

The surface area of a cylinder is define by the formula S.A.=2πrh+2<span>πr^2, where the first part of the formula refers to the lateral area, perimeter, or circumference and the second part to the area of the bases, which are circles.
On this exercise it is asked to find the lateral area of a cylinder whose radius is 6 cm, and has a height of 20cm. To find the lateral area of the cylinder you should substitute this values into the formula, S.A.=2</span>πrh, and as can be seen the answers are given in terms of <span>π or pi.
S.A.=2</span><span>πrh
S.A.=2</span><span>π(6cm)(20cm)
S.A.=2</span><span>π(120cm)
S.A.=240</span>π cm^2
The lateral area of the cylinder is 240<span>π cm^2 or in other words letter B from the given choices.</span>
